Web browser developed by Google

This article is about the web browser. For the engage system, see Chrome OS. For other uses, see Chrome ( disambiguation )

Google Chrome is a cross-platform vane browser developed by Google. It was first released in 2008 for Microsoft Windows, built with unblock software components from Apple WebKit and Mozilla Firefox. [ 15 ] It was subsequently ported to Linux, macOS, io, and Android, where it is the default option browser. [ 16 ] The browser is besides the independent component of Chrome OS, where it serves as the platform for network applications. Most of Chrome ‘s source code comes from Google ‘s absolve and open-source software project Chromium, but Chrome is licensed as proprietorship freeware. [ 14 ] WebKit was the original render locomotive, but Google finally forked it to create the Blink engine ; [ 17 ] all Chrome variants except io immediately use Blink. [ 18 ] As of October 2021, StatCounter estimates that Chrome has a 68 % worldwide browser market share ( after peaking at 72.38 % in November 2018 ) on personal computers ( personal computer ), [ 19 ] is most used on tablets ( having surpassed Safari ), and is besides dominant on smartphones, [ 20 ] [ 21 ] and at 65 % across all platforms combined. [ 22 ] Because of this success, Google has expanded the “ Chrome ” brand list to other products : Chrome OS, Chromecast, Chromebook, Chromebit, Chromebox, and Chromebase .


Google CEO Eric Schmidt opposed the development of an freelancer web browser for six years. He stated that “ at the time, Google was a little company ”, and he did not want to go through “ bruising browser wars “. After co-founders Sergey Brin and Larry Page hired several Mozilla Firefox developers and built a demonstration of Chrome, Schmidt said that “ It was indeed good that it basically forced me to change my thinker. ” [ 23 ] In September 2004, rumors of Google building a web browser first appeared. Online journals and U.S. newspapers stated at the time that Google was hiring erstwhile Microsoft web developers among others. It besides came shortly after the release of Mozilla Firefox 1.0, which was surging in popularity and taking market share from Internet Explorer, which had noted security problems. [ 24 ] Development of the browser began in 2006 [ 25 ] spearheaded by Sundar Pichai. [ 26 ]


The release announcement was primitively scheduled for September 3, 2008, and a comedian by Scott McCloud was to be sent to journalists and bloggers explaining the features within the raw browser. [ 27 ] Copies intended for Europe were shipped early and german blogger Philipp Lenssen of Google Blogoscoped made a scan copy of the 38-page comedian available on his web site after receiving it on September 1, 2008. [ 28 ] [ 29 ] Google subsequently made the amusing available on Google Books, [ 30 ] and mentioned it on their official blog along with an explanation for the early release. The product was named “ Chrome ” as an initial exploitation project code mention, because it is associated with fast cars and speed. Google kept the development visualize name as the concluding acquittance identify, as a “ brash ” or ironic nickname, as one of the main aims was to minimize the exploiter interface chrome. [ 32 ] [ 33 ]

Public release

An early version of Chromium for Linux, explaining the dispute between Chrome and Chromium The browser was beginning publicly released, formally as a beta version, [ 34 ] on September 2, 2008 for Windows XP and newer, and with support for 43 languages, and belated as a “ stable ” public passing on December 11, 2008. On that like day, a CNET news item drew care to a passage in the Terms of Service statement for the initial beta release, which seemed to grant to Google a license to all capacity transferred via the Chrome browser. [ 35 ] This enactment was inherited from the general Google terms of servicing. [ 36 ] Google responded to this criticism immediately by stating that the terminology used was borrowed from other products, and removed this passage from the Terms of Service. [ 14 ] Chrome promptly gained about 1 % custom parcel. [ 37 ] [ 38 ] After the initial surge, custom partake dropped until it hit a low of 0.69 % in October 2008. It then started rising again and by December 2008, Chrome again passed the 1 % threshold. [ 39 ] In early January 2009, CNET reported that Google planned to release versions of Chrome for OS X and Linux in the beginning half of the year. [ 40 ] The first official Chrome OS X and Linux developer previews were announced on June 4, 2009, [ 41 ] with a blog post saying they were missing many features and were intended for early feedback rather than general use. [ 42 ] In December 2009, Google released beta versions of Chrome for OS X and Linux. [ 43 ] [ 44 ] Google Chrome 5.0, announced on May 25, 2010, was the first static release to support all three platforms. [ 45 ] Chrome was one of the twelve browsers offered on to European Economic Area users of Microsoft Windows in 2010. [ 46 ]


Chrome was assembled from 25 different code libraries from Google and third parties such as Mozilla ‘s Netscape Portable Runtime, Network Security Services, NPAPI ( dropped as of adaptation 45 ), [ 47 ] Skia Graphics Engine, SQLite, and a number of other open-source projects. [ 48 ] The V8 JavaScript virtual machine was considered a sufficiently crucial project to be split murder ( as was Adobe / Mozilla ‘s Tamarin ) and handled by a separate team in Denmark coordinated by Lars Bak in Aarhus. According to Google, existing implementations were designed “ for little programs, where the operation and interactivity of the system were n’t that important ”, but world wide web applications such as Gmail “ are using the vane browser to the fullest when it comes to DOM manipulations and JavaScript “, and consequently would significantly benefit from a JavaScript engine that could work faster. Chrome initially used the WebKit rendering locomotive to display web pages. In 2013, they forked the WebCore part to create their own layout locomotive Blink. Based on WebKit, Blink merely uses WebKit ‘s “ WebCore ” components, while substituting other components, such as its own multi-process architecture, in home of WebKit ‘s native execution. [ 17 ] Chrome is internally tested with unit test, automated test of scripted exploiter actions, fuzz quiz, a well as WebKit ‘s layout tests ( 99 % of which Chrome is claimed to have passed ), and against normally accessed websites inside the Google index within 20–30 minutes. [ 30 ] Google created Gears for Chrome, which added features for web developers typically relating to the build of vane applications, including offline corroborate. [ 30 ] Google phased out Gears as the lapp functionality became available in the HTML5 standards. [ 49 ] In March 2011, Google introduced a new simplified logo to replace the previous 3D logo that had been used since the plan ‘s origin. Google interior designer Steve Rura explained the caller reasoning for the change : “ Since Chrome is all about making your web experience as easy and clutter-free as possible, we refreshed the Chrome picture to better represent these sentiments. A simple icon embodies the Chrome emotional state – to make the web quick, lighter, and easier for all. ” [ 50 ] On January 11, 2011, the Chrome product coach, Mike Jazayeri, announced that Chrome would remove H.264 television codec support for its HTML5 musician, citing the desire to bring Google Chrome more in line with the presently available afford codecs available in the Chromium undertaking, which Chrome is based on. [ 51 ] Despite this, on November 6, 2012, Google released a version of Chrome on Windows which added hardware-accelerated H.264 video decoding. [ 52 ] In October 2013, Cisco announced that it was open-sourcing its H.264 codecs and would cover all fees required. [ 53 ] On February 7, 2012, Google launched Google Chrome Beta for Android 4.0 devices. [ 54 ] On many new devices with Android 4.1 and late preinstalled, Chrome is the nonpayment browser. [ 55 ] In May 2017, Google announced a interpretation of Chrome for augment world and virtual reality devices. [ 56 ]

Version history


Google Chrome features a minimalistic drug user interface, with its user-interface principles later being implemented into other browsers. For case, the confluence of the address bar and research cake into the omnibox or omnibar [ 57 ] [ 58 ] Chrome besides has a reputation for strong browser performance. [ 59 ] [ 60 ]

web standards support

The results of the Acid3 test on Google Chrome 4.0 The beginning release of Google Chrome passed both the Acid1 and Acid2 tests. Beginning with version 4.0, Chrome has passed all aspects of the Acid3 screen. [ 61 ] As of May 2011, Chrome has identical good support for JavaScript/ ECMAScript according to Ecma International ‘s ECMAScript standards conformity Test 262 [ 62 ] ( version ES5.1 May 18, 2012 ). This test reports as the final mark the number of tests a browser failed ; hence lower scores are good. In this test, Chrome version 37 scored 10 failed/11,578 passed. For comparison, Firefox 19 scored 193 failed/11,752 passed and Internet Explorer 9 has a grade of 600+ failed, while Internet Explorer 10 has a score of 7 failed. In 2011, on the official CSS 2.1 examination suite by standardization organization W3C, WebKit, the Chrome render engine, passes 89.75 % ( 89.38 % out of 99.59 % covered ) CSS 2.1 tests. [ 63 ] On the HTML5 web standards trial, Chrome 41 scores 518 out of 555 points, placing it ahead of the five most popular background browsers. [ 64 ] [ 65 ] Chrome 41 on Android scores 510 out of 555 points. [ 66 ] [ 67 ] [ 68 ] Chrome 44 scores 526, only 29 points less than the maximum score. [ 69 ]

User interface

Google Chrome logo 2D motif from March 2011 until October 2015Material Design motif used from September 2014 onward for mobile versions and October 2015 onward for desktop versions New Google Chrome logo from 2022. It has increased brightness and clearness than the previous logo. By default, the main exploiter interface includes binding, forward, refresh/cancel and menu buttons. A base button is not shown by default, but can be added through the Settings page to take the drug user to the new tab key page or a custom home page. [ 70 ] Tabs are the chief component of Chrome ‘s user interface and have been moved to the top of the window quite than below the controls. This insidious variety contrasts with many existing tabbed browsers which are based on windows and control tabs. Tabs, with their state, can be transferred seamlessly between window containers by dragging. Each yellow journalism has its own set of controls, including the Omnibox. [ 30 ] The Omnibox is a URL box that combines the functions of both the address bar and search box. If a drug user enters the URL of a locate previously searched from, Chrome allows pressing Tab to search the site again directly from the Omnibox. When a user starts typing in the Omnibox, Chrome provides suggestions for previously visited sites ( based on the URL or in-page textbook ), democratic websites ( not necessarily visited before – powered by Google Instant ), and popular searches. Although Instant can be turned off, suggestions based on previously visited sites can not be turned off. Chrome will besides autocomplete the URLs of sites visited much. [ 30 ] If a user types keywords into the Omnibox that do n’t match any previously visited websites and presses enter, Chrome will conduct the search using the default search engine. One of Chrome ‘s speciate features is the New Tab Page, which can replace the browser home page and is displayed when a new tab is created. in the first place, this showed thumbnails of the nine most inflict websites, along with frequent searches, holocene bookmarks, and recently closed tab key ; alike to Internet Explorer and Firefox with Google Toolbar, or Opera ‘s Speed Dial. [ 30 ] In Google Chrome 2.0, the New Tab Page was updated to allow users to hide thumbnails they did not want to appear. [ 71 ] Starting in adaptation 3.0, the New Tab Page was revamped to display thumbnails of the eight most inflict websites. The thumbnails could be rearranged, pinned, and removed. alternatively, a list of text links could be displayed alternatively of thumbnails. It besides features a “ recently closed ” bar that shows recently closed tab and a “ tips ” department that displays hints and tricks for using the browser. [ 72 ] Starting with Google Chrome 3.0, users can install themes to alter the appearance of the browser. [ 73 ] many free third-party themes are provided in an on-line gallery, [ 74 ] accessible through a “ Get themes ” button in Chrome ‘s options. [ 75 ] Chrome includes a bookmarks hierarchical menu that lists the user ‘s bookmarks, provides easy access to Chrome ‘s Bookmark Manager, and allows the drug user to toggle a bookmarks bar on or off. On January 2, 2019, Google introduced Native Dark Theme for Chrome on Windows 10. [ 76 ]

Starting with Google Chrome 4.1 the lotion added a built-in transformation banish using Google Translate. Language translation is presently available for 52 languages. [ 77 ] When Chrome detects a alien language other than the user ‘s prefer terminology set during the installation clock time, it asks the user whether or not to translate. Chrome allows users to synchronize their bookmarks, history, and settings across all devices with the browser installed by sending and receiving data through a chosen Google Account, which in twist updates all signed-in instances of Chrome. This can be authenticated either through Google credentials, or a synchronize passphrase. For web developers, Chrome features an component examiner which allows users to look into the DOM and see what makes up the web page. [ 78 ] Chrome has particular URLs that load application-specific pages rather of websites or files on harrow. Chrome besides has a built-in ability to enable experimental features. in the first place called about:labs, the address was changed to about:flags to make it less obvious to casual users. [ 79 ] [ 80 ] The background edition of Chrome is able to save pages as HTML with assets in a “ _files ” subfolder, or as unprocessed HTML-only document. It besides offers an option to save in the MHTML format. [ 81 ]

Desktop shortcuts and apps

Chrome allows users to make local desktop shortcuts that open world wide web applications in the browser. The browser, when opened in this way, contains none of the regular interface except for the style bar, thus as not to “ interrupt anything the exploiter is trying to do ”. This allows network applications to run aboard local software ( exchangeable to Mozilla Prism and Fluid ). [ 30 ] This sport, according to Google, would be enhanced with the Chrome Web Store, a one-stop web-based vane applications directory which opened in December 2010. [ 82 ] [ 83 ] In September 2013, Google started making Chrome apps “ For your desktop ”. This mean offline access, desktop shortcuts, and less dependence on Chrome—apps launch in a window branch from Chrome, and look more like native applications. [ 84 ]

Chrome Web Store

Announced on December 7, 2010, the Chrome Web Store allows users to install web applications as extensions to the browser, although most of these extensions function plainly as links to popular web pages and/or games, some of the apps like Springpad do provide excess features like offline access. The themes and extensions have besides been tightly integrated into the new store, allowing users to search the entire catalog of Chrome extras. [ 85 ] The Chrome Web Store was opened on February 11, 2011, with the free of Google Chrome 9.0. [ 86 ]


Browser extensions are able to modify Google Chrome. They are supported by the browser ‘s background edition. [ 87 ] These extensions are written using web technologies like HTML, JavaScript, and CSS. [ 88 ] They are distributed through Chrome Web Store, [ 89 ] initially known as the Google Chrome Extensions Gallery. [ 87 ] On September 9, 2009, Google enabled extensions by default on Chrome ‘s developer distribution channel, and provided several sample extensions for testing. [ 90 ] In December, the Google Chrome Extensions Gallery beta began with approximately 300 extensions. [ 44 ] [ 91 ] It was launched on January 25, 2010, along with Google Chrome 4.0, containing approximately 1500 extensions. [ 92 ] In 2014, Google started preventing some Windows users from installing extensions not hosted on the Chrome Web Store. [ 93 ] [ 94 ] The follow year Google reported a “ 75 % drop in customer patronize help requests for uninstalling unwanted extensions ” which led them to expand this limitation to all Windows and Mac users. [ 95 ]

luminary examples


The JavaScript virtual machine used by Chrome, the V8 JavaScript locomotive, has features such as dynamic code generation, hidden class transitions, and precise garbage collection. [ 30 ] In 2008, several websites performed benchmark tests using the SunSpider JavaScript Benchmark tool a well as Google ‘s own hardening of computationally acute benchmarks, which include beam trace and constraint resolution. [ 99 ] They unanimously reported that Chrome performed a lot faster than all competitors against which it had been tested, including Safari ( for Windows ), Firefox 3.0, Internet Explorer 7, Opera, and Internet Explorer 8. [ 100 ] [ 101 ] [ 102 ] [ 59 ] { [ 103 ] [ 104 ] however, on October 11, 2010, independent tests of JavaScript performance, Chrome has been scoring just behind Opera ‘s Presto engine since it was updated in interpretation 10.5. [ 105 ] On September 3, 2008, Mozilla responded by stating that their own TraceMonkey JavaScript engine ( then in beta ), was faster than Chrome ‘s V8 engine in some tests. [ 106 ] [ 107 ] [ 108 ] John Resig, Mozilla ‘s JavaScript evangelist, foster commented on the performance of different browsers on Google ‘s own suite, commenting on Chrome ‘s “ decimating ” of the other browsers, but he questioned whether Google ‘s cortege was congressman of real programs. He stated that Firefox 3.0 performed ailing on recursion -intensive benchmarks, such as those of Google, because the Mozilla team had not implemented recursion-tracing so far. [ 109 ] Two weeks after Chrome ‘s plunge in 2008, the WebKit team announced a new JavaScript engine, pinfish Extreme, [ 110 ] citing a 36 % speed improvement over Chrome ‘s V8 engine. [ 111 ] [ 112 ] [ 113 ] Like most major web browsers, Chrome uses DNS prefetching to speed up web site lookups, [ 78 ] as do early browsers like Firefox, [ 114 ] Safari, [ 115 ] Internet Explorer ( called DNS Pre-resolution ), [ 116 ] and in Opera as a UserScript ( not built-in ). [ 117 ] Chrome once used their now-deprecated SPDY protocol rather of merely HTTP [ 118 ] [ 119 ] when communicating with servers that support it, such as Google services, Facebook, Twitter. SPDY support was removed in Chrome translation 51. This was due to SPDY being replaced by HTTP/2, a standard that was based upon it. In November 2019, Google said it was working on several “ speed badge ” systems that let visitors know why a page is taking time to show up. The variations include simple text warnings and more subtle signs that indicate a site is slow. No date has been given for when the badge system will be included with the Chrome browser. [ 120 ] Chrome once supported a Data Saver feature for making pages load faster called Lite Mode. [ 121 ] Previously, Chrome engineers Addy Osmani and Scott Little announced Lite Mode would automatically lazy-load images and iframes for faster foliate loads. [ 122 ] Lite Mode was switched off in Chrome 100, citing a decrease in mobile data costs for many countries. [ 123 ]


Chrome sporadically retrieves updates of two blacklists ( one for phishing and one for malware ), and warns users when they attempt to visit a site flagged as potentially harmful. This serve is besides made available for habit by others via a free public API called “ Google Safe Browsing API ”. [ 30 ] Chrome uses a process-allocation model to sandbox tabs. [ 124 ] Using the principle of least privilege, each yellow journalism process can not interact with critical memory functions ( e.g. OS memory, drug user files ) or other tab processes – alike to Microsoft ‘s “ Protected Mode ” used by Internet Explorer 9 or greater. The Sandbox Team is said to have “ taken this existing process limit and made it into a jail “. This enforces a computer security model whereby there are two levels of multilevel security ( user and sandbox ) and the sandbox can lone respond to communication requests initiated by the user. [ 125 ] On Linux sandboxing uses the seccomp modality. [ 126 ] [ 127 ] In January 2015, TorrentFreak reported that using Chrome when connected to the internet using a VPN can be a serious security issue due to the browser ‘s support for WebRTC. [ 128 ] On September 9, 2016, it was reported that starting with Chrome 56, users will be warned when they visit insecure HTTP websites to encourage more sites to make the transition to HTTPS. [ 129 ] On December 4, 2018, Google announced its Chrome 71 let go of with newfangled security features, including a built-in ad sport system. In addition, Google besides announced its plan to crack down on websites that make people involuntarily subscribe to mobile subscription plans. [ 130 ] On September 2, 2020, with the publish of Chrome 85, Google extended support for Secure DNS in Chrome for Android. DNS-over-HTTPS ( DoH ), was designed to improve condom and privacy while browsing the web. Under the update, Chrome mechanically switches to DNS-over-HTTPS ( DoH ), if the current DNS supplier supports the sport. [ 131 ]

Password management


Since 2008, Chrome has been faulted for not including a master password to prevent casual access to a drug user ‘s passwords. Chrome developers have indicated that a master password does not provide very security system against determined hackers and have refused to implement one. Bugs filed on this exit have been marked “ WontFix ”. [ 132 ] [ 133 ] As of February 2014, Google Chrome asks the drug user to enter the Windows account password before showing saved passwords. [ 134 ]


On Linux, Google Chrome/Chromium can store passwords in three ways : GNOME Keyring, KWallet or plain text. Google Chrome/Chromium chooses which store to use automatically, based on the background environment in habit. [ 135 ] Passwords stored in GNOME Keyring or KWallet are encrypted on disk, and access to them is controlled by dedicated devil software. Passwords stored in plain text are not encrypted. Because of this, when either GNOME Keyring or KWallet is in function, any unencrypted passwords that have been stored previously are mechanically moved into the code store. support for using GNOME Keyring and KWallet was added in adaptation 6, but using these ( when available ) was not made the default mode until interpretation 12 .


As of interpretation 45, the Google Chrome password director is no long integrated with Keychain, since the interoperability goal is nobelium longer potential. [ 136 ]

security vulnerabilities

No security vulnerabilities in Chrome were exploited in the three years of Pwn2Own from 2009 to 2011. [ 137 ] At Pwn2Own 2012, Chrome was defeated by a french team who used zero day exploits in the version of Flash shipped with Chrome to take complete control of a amply patched 64-bit Windows 7 personal computer using a booby-trapped web site that overcame Chrome ‘s sandboxing. [ 138 ] Chrome was compromised twice at the 2012 CanSecWest Pwnium. [ 138 ] [ 139 ] [ 140 ] Google ‘s official reception to the exploits was delivered by Jason Kersey, who congratulated the researchers, noting “ We besides believe that both submissions are works of art and deserve wide-eyed share and recognition. ” [ 141 ] Fixes for these vulnerabilities were deployed within 10 hours of the submission. [ 142 ] [ 143 ] A significant number of security vulnerabilities in Chrome occur in the Adobe Flash Player. For example, the 2016 Pwn2Own successful attack on Chrome relied on four security vulnerabilities. Two of the vulnerabilities were in Flash, one was in Chrome, and one was in the Windows kernel. [ 144 ] In 2016, Google announced that it was planning to phase out Flash Player in Chrome, starting in version 53. The first phase of the plan is to disable Flash for ads and “ backdrop analytics ”, with the ultimate goal of disabling it completely by the end of the year, except on specific sites that Google has deemed to be broken without it. Flash would then be re-enabled with the excommunication of ads and background analytics on a site-by-site basis. [ 145 ] Leaked documents published by WikiLeaks, codenamed Vault 7 and dated from 2013 to 2016, detail the capabilities of the CIA, such as the ability to compromise web browsers ( including Google Chrome ). [ 146 ] [ 147 ]

Malware blocking and ad freeze

Google introduced download scanning protection in Chrome 17. [ 148 ] In February 2018, Google introduced an ad block feature based on recommendations from the Interactive Advertising Bureau. Sites that hire invasive ads are given a 30-day warning, after which their ads will be blocked. [ 149 ] Consumer Reports recommended users install dedicated ad-blocking tools alternatively, which offer increase security against malware and track. [ 150 ]


  • Chrome supported, up to version 45, plug-ins with the Netscape Plugin Application Programming Interface (NPAPI),[151] so that plug-ins (for example Adobe Flash Player) run as unrestricted separate processes outside the browser and cannot be sandboxed as tabs are. ActiveX is not supported.[151] Since 2010, Adobe Flash has been integral to Chrome and does not need be installed separately. Flash is kept up to date as part of Chrome’s own updates.[152] Java applet support was available in Chrome with Java 6 update 12 and above.[153] Support for Java under OS X was provided by a Java Update released on May 18, 2010.[154]
  • On August 12, 2009, Google introduced a replacement for NPAPI that is more portable and more secure[155] called Pepper Plugin API (PPAPI).[156] The default bundled PPAPI Flash Player (or Pepper-based Flash Player) was available on Chrome OS first, then replaced the NPAPI Flash Player on Linux from Chrome version 20, on Windows from version 21 (which also reduced Flash crashes by 20%),[157] and eventually came to OS X at version 23.[158]
  • On September 23, 2013, Google announced that it would be deprecating and then removing NPAPI support. NPAPI support was removed from Linux in Chrome release 35.[159] NPAPI plugins like Java can no longer work in Chrome (but there are workarounds for Flash by using PPAPI Flash Player on Linux including for Chromium).[160]
  • On April 14, 2015, Google released Chrome v42, disabling the NPAPI by default. This makes plugins that do not have a PPAPI plugin counterpart incompatible with Chrome, such as Java, Silverlight and Unity. However, NPAPI support could be enabled through the chrome://flags permanent absolutely associate] menu, until the release of version 45 on September 1, 2015, that removed NPAPI support entirely.[161]


Incognito mode

“ Incognito mode ” redirects here. For early uses, see Incognito Google Chrome Incognito modality message The private browse sport called Incognito manner prevents the browser from locally storing any history data, cookies, site data, or form inputs. [ 162 ] Downloaded files and bookmarks will be stored. In addition, exploiter activity is not hidden from visited websites or the Internet overhaul provider. Incognito manner is similar to the private shop feature in other vane browsers. It does not prevent saving in all windows : “ You can switch between an incognito window and any unconstipated windows you have unfold. You ‘ll lone be in incognito manner when you ‘re using the incognito window ”. [ 163 ] The io version of Chrome besides supports the optional ability to lock incognito tabs with Face ID, Touch ID or the device ‘s passcode. [ 164 ]

Listening capabilities

In June 2015, the Debian developer community discovered that Chromium 43 and Chrome 43 were programmed to download the Hotword Shared Module, which could enable the OK Google voice recognition extension, although by default option it was “ off ”. This raised privacy concerns in the media. [ 165 ] [ 166 ] The module was removed in Chrome 45, which was released on September 1, 2015, and was entirely introduce in Chrome 43 and 44. [ 167 ] [ 168 ]

User track concerns

Chrome sends details about its users and their activities to Google through both optional and non-optional drug user tracking mechanisms. [ 169 ] [ 170 ] Some of the tracking mechanisms can be optionally enabled and disabled through the initiation interface [ 171 ] and through the browser ‘s options dialogue. [ 172 ] Unofficial builds, such as SRWare Iron, seek to remove these features from the browser wholly. [ 173 ] The RLZ feature is not included in the Chromium browser either. [ 174 ] In March 2010, Google devised a new method acting to collect installation statistics : the unique ID keepsake included with Chrome is now used for only the first connection that Google Update makes to its server. [ 175 ] The optional trace service included in Google Chrome has been criticized because it provides the information typed into the Omnibox to the search provider before the user even hits render. This allows the search engine to provide URL suggestions, but besides provides them with web use information tied to an IP address. [ 176 ] The optional feature to use a web service to help resolve spelling errors has privacy implications. [ 177 ] A 2019 review by Washington Post engineering columnist Geoffrey A. Fowler found that in a typical week of browse, Chrome allowed thousands of more cookies to be stored than Mozilla Firefox. Fowler pointed out that because of its advertise businesses, despite the privacy controls it offers users, Google is a major producer of third-party cookies and has a fiscal interest in collecting user data ; he recommended switching to Firefox, Apple Safari, or Chromium-based Brave. [ 178 ] In January 2021, Alphabet stated it was making advancement on developing privacy-friendly alternatives which would replace third-party cookies presently being used by advertisers and companies to track browsing habits. Google has promised to phase out the practice of cookies in their web-browser in 2022, implementing their FLoC technology rather. The announcement came after scrutiny from both the United States and the United Kingdom : the U.K. ‘s Competition and Markets Authority opened a conventional probe into Google ‘s claim to end cookie support in January of the same year and the antimonopoly lawsuit against the company in December 2020 by ten U.S. states. [ 179 ] [ 180 ] [ 181 ] [ 182 ] Chrome ‘s future switch to FLoC had drawn criticism from DuckDuckGo, Brave and the Electronic Frontier Foundation. [ 183 ] [ 184 ] [ 185 ] On January 25, 2022, Google announced it had killed off development of its FLoC technologies and proposed the fresh Topics API to replace it. Topics is similarly aimed at removing third-party cookies, using one ‘s weekly web bodily process to determine a located of five interests. Topics is supposed to refresh every three weeks, changing the type of ads served the user and not retaining the gathered data. [ 186 ] [ 187 ]

Chrome previously was able to suggest like pages when a page could not be found. For this, in some cases Google servers were contacted. [ 192 ] The feature has since been removed .

Do not Track

In February 2012, Google announced that Chrome would implement the Do not Track ( DNT ) criterion to inform websites the exploiter ‘s desire not to be tracked. The protocol was implemented in version 23. In line with the W3 ‘s draft standard for DNT, [ 193 ] it is turned off by default in Chrome. [ 194 ]


Screenshot of a Chrome browser crash A multi-process computer architecture is implemented in Chrome where, by default, a separate process is allocated to each locate exemplify and plugin. [ 195 ] This operation is term process isolation, [ 196 ] and raises security and stability by preventing tasks from interfering with each other. An attacker successfully gaining access to one application gains access to no others, [ 197 ] and failure in one example results in a Sad Tab screen of death, similar to the long-familiar Sad Mac, but merely one pill crashes rather of the unharmed application. This strategy exacts a repair per-process monetary value up front, but results in less memory bloat over time as fragmentation is confined to each exemplify and no longer needs further memory allocations. [ 30 ] This architecture was belated adopted in Safari [ 198 ] and Firefox. [ 199 ] Chrome includes a process management utility called Task Manager which lets users see what sites and plugins are using the most memory, downloading the most bytes and overusing the CPU and provides the ability to terminate them. [ 30 ] Chrome Version 23 ensures its users an better battery life for the systems supporting Chrome ‘s GPU accelerated video decoding. [ 200 ] [ 52 ]

The first gear production handout on December 11, 2008, marked the end of the initial Beta test period and the get down of production. shortly thereafter, on January 8, 2009, Google announced an updated spill system with three channels : stable ( corresponding to the traditional production ), Beta, and Developer preview ( besides called the “ Dev ” distribution channel ). Where there were before only two channels : Beta and Developer, immediately there were three. concurrently, all Developer channel users were moved to the Beta channel along with the promoted Developer secrete. Google explained that now the Developer transmit builds would be less stable and polish than those from the initial Google Chrome ‘s Beta period. Beta users could opt back to the Developer transmit as desired. Each groove has its own secrete cycle and stability level. The stable channel updated roughly quarterly, with features and fixes that passed “ exhaustive ” testing in the Beta transmit. Beta updated roughly monthly, with “ static and accomplished ” features migrated from the Developer groove. The Developer channel updated once or twice per week and was where ideas and features were first publicly exposed “ ( and sometimes fail ) and can be very unstable at times ”. [ Quoted remarks from Google ‘s policy announcements. ] [ 201 ] [ 202 ] [ 203 ]
Google Chrome Canary application picture On July 22, 2010, Google announced it would ramp up the speed at which it releases new stable versions ; the release cycles were shortened from quarterly to six weeks for major stable updates. [ 204 ] Beta channel releases nowadays come roughly at the like rate as stable releases, though approximately one calendar month in promote, while Dev impart releases appear roughly once or doubly weekly, allowing meter for basic release-critical examination. [ 205 ] This faster release bicycle besides brought a fourth channel : the “ Canary ” distribution channel, update daily from a build produced at 09:00 coordinated universal time from the most stable of the end 40 revisions. [ 206 ] The name refers to the rehearse of using canaries in coal mines, so if a switch “ kills ” Chrome Canary, it will be blocked from migrating down to the Developer channel, at least until fixed in a subsequent Canary build up. [ 207 ] Canary is “ the most bleeding-edge official version of Chrome and reasonably of a desegregate between Chrome dev and the Chromium snapshot builds ”. Canary releases run side by side with any early channel ; it is not linked to the early Google Chrome initiation and can therefore run different synchronization profiles, themes, and browser preferences. This ensures that disengagement functionality remains even when some Canary updates may contain release-breaking bugs. [ 208 ] It does not natively include the option to be the default browser, although on Windows and OS X it can be set through System Preferences. Canary was Windows-only at first ; an OS X version was released on May 3, 2011. [ 209 ] The Chrome beta distribution channel for Android was launched on January 10, 2013 ; like Canary, it runs side by side with the static channel for Android. [ 210 ] [ 211 ] Chrome Dev for Android was launched on April 29, 2015. [ 212 ] All Chrome channels are mechanically distributed according to their respective secrete cycles. The mechanism differs by chopine. On Windows, it uses Google Update, and auto-update can be controlled via Group Policy. [ 213 ] alternatively, users may download a standalone installer of a version of Chrome that does not auto-update. [ 214 ] [ 215 ] On OS X, it uses Google Update Service, and auto-update can be controlled via the OS X “ defaults ” system. [ 216 ] On Linux, it lets the organization ‘s normal box management arrangement supply the updates. This auto-updating behavior is a key remainder from Chromium, the non-branded open-source browser which forms the kernel of Google Chrome. Because Chromium besides serves as the pre-release development trunk for Chrome, its revisions are provided as generator code and buildable snapshots are produced endlessly with each new entrust, requiring users to manage their own browser updates. [ 217 ] In March 2021, Google announced that starting with Chrome 94 in the third quarter of 2021, Google Chrome Stable releases will be made every four weeks, alternatively of six weeks as they have been since 2010. besides, Google announced a newfangled free channel for system administrators and browser embedders with releases every eight weeks. [ 218 ]

Release adaptation numbers

Releases are identified by a four-part translation count, e.g. 42.0.2311.90 ( Windows Stable release April 14, 2015 [ 219 ] ). The components are [ 220 ] [ 221 ]

Major.minor reflects scheduling policy
Build.patch identifies content progression
  • Major represents a product release. These are scheduled 7–8 per year, unlike other software systems where the major version number updates only with substantial new content.
  • Minor is usually 0. References to version ‘x’ or ‘x.0’, e.g. 42.0, refer to this major.minor designation.
  • Build is ever increasing. For a release cycle, e.g. 42.0, there are several builds in the Canary and Developer period. The last build number from Developer is kept throughout Beta and Stable and is locked with the major.minor for that release.
  • Patch resets with each build, incrementing with each patch. The first patch is 0, but usually the first publicly released patch is somewhat higher. In Beta and Stable, only patch increments.

chromium and Chrome dismissal schedules are linked through Chromium ( Major ) interpretation Branch Point dates, published annually. [ 220 ] The Branch Points precede the final Chrome Developer build ( initial ) handout by 4 days ( about always ) and the Chrome Stable initial passing by approximately 53 days. [ 222 ] exemplar : The version 42 Branch Point was February 20, 2015. [ 220 ] Developer builds stopped advancing at build 2311 with turn 42.0.2311.4 on February 24, [ 223 ] 4 days subsequently. The first gear static spill, 42.0.2311.90, was April 14, 2015, [ 219 ] 53 days after the Branch Point .

Color management

Chrome supports color management by using the system-provided ICC v2 and v4 support on macOS, and from adaptation 22 supports ICC v2 profiles by default on other platforms. [ 224 ]

Dinosaur Game

In Chrome, when not connected to the Internet and an error message displaying “ No internet ” is shown, on the lead, an “ 8-bit “ Tyrannosaurus rex is shown, but when pressing the distance prevention on a keyboard, mouse-clicking on it or tapping it on touch devices, the T-Rex instantaneously jumps once and dashes across a cactus -ridden desert, revealing it to be an Easter egg in the form of a platform game. [ 225 ] [ 226 ] [ 227 ] [ 228 ] The game itself is an infinite runner, and there is no time limit in the game as it progresses faster and sporadically tints to a black background. A school Chromebook administrator can disable the game. [ 229 ]


The current version of Chrome runs on :
As of April 2016, stable 32-bit and 64-bit builds are available for Windows, with entirely 64-bit stable builds available for Linux and macOS. [ 231 ] [ 232 ] [ 233 ] 64-bit Windows builds became available in the developer channel and as canary builds on June 3, 2014, [ 234 ] in the beta channel on July 30, 2014, [ 235 ] and in the stable channel on August 26, 2014. [ 236 ] 64-bit OS X builds became available as canary yellow builds on November 7, 2013, [ 237 ] in the beta distribution channel on October 9, 2014, [ 238 ] and in the stable distribution channel on November 18, 2014. [ 231 ] Starting with the publish of interpretation 89, Chrome will merely be supported on Intel / Intel x86 and AMD processors with the SSE3 teaching set up. [ 239 ] [ 240 ] [ 241 ]


Google Chrome running on an Android telephone A beta adaptation for Android 4.0 devices was launched on February 7, 2012, available for a limited number of countries from Google Play. [ 246 ] [ 247 ] celebrated features : synchronization with desktop Chrome to provide the same bookmarks and view the same browser tab, [ 248 ] page pre-rendering, [ 249 ] hardware acceleration. [ 250 ] many of the latest HTML5 features : about all of the Web Platform ‘s features : GPU-accelerated canvass, including CSS 3D Transforms, CSS animations, SVG, WebSocket ( including binary messages ), dedicated Workers ; it has bubble over scroll support, hard HTML5 video support, and new capabilities such as IndexedDB, WebWorkers, Application Cache and the File APIs, date- and time-pickers, parts of the Media Capture API. [ 249 ] [ 251 ] besides supports mobile oriented features such as Device Orientation and Geolocation. [ 251 ] mobile customizations : swipe gesticulate tab key switch, [ 248 ] liaison preview allows zooming in on ( multiple ) links to ensure the desire one is clicked, [ 248 ] baptismal font size boosting to ensure readability careless of the zoom degree. [ 251 ] Features missing in the fluid version include sandboxed tabs, [ 249 ] Safe Browsing, [ 249 ] apps or extensions, [ 250 ] Adobe Flash ( now and in the future ), [ 250 ] Native Client, [ 250 ] and the ability to export exploiter data such a list of their afford tabs or their browse history into portable local anesthetic files. [ 252 ] Development changes : distant debug, [ 249 ] [ 253 ] part of the browser layer has been implemented in Java, communicating with the stay of the Chromium and WebKit code through Java Native Bindings. [ 251 ] The code of Chrome for Android is a fork of the Chromium project. It is a precedence to upstream most new and modify code to Chromium and WebKit to resolve the fork. [ 251 ] The April 17, 2012 update included handiness in 31 extra languages and in all countries where Google Play is available. A desktop version of a web site can besides be requested as opposed to a mobile adaptation. In addition, Android users can now add bookmarks to their Android base screens if they choose and decide which apps should handle links opened in Chrome. [ 254 ] On June 27, 2012, Google Chrome for Android exited beta and became stable. [ 255 ] [ 256 ] Chrome 18.0.1026311, released on September 26, 2012, was the first version of Chrome for Android to support mobile devices based on Intel x86. [ 257 ] Starting from interpretation 25, the Chrome adaptation for Android is aligned with the background translation, and normally newly stable releases are available at the lapp time between the Android and the desktop adaptation. Google released a disjoined Chrome for Android beta channel on January 10, 2013, with version 25. [ 210 ] As of 2013 a break beta adaptation of Chrome is available in the Google Play Store – it can run side by side with the stable liberation. [ 258 ]


Chrome is available on Apple ‘s fluid io operating organization as Google Chrome for iOS. Released in the Apple App Store on June 26, 2012, it supports the iPad, iPhone, and iPod Touch, and the current version requires that the device has iOS 12.0 or greater installed. [ 259 ] In accordance with Apple ‘s requirements for browsers released through their App Store, this version of Chrome uses the iOS WebKit – which is Apple ‘s own mobile rendering engine and components, developed for their Safari browser – therefore it is restricted from using Google ‘s own V8 JavaScript engine. [ 260 ] [ 261 ] Chrome is the default web browser for the io Gmail application. In a review by Chitika, Chrome was noted as having 1.5 % of the io web browser market as of July 18, 2012. [ 262 ] In October 2013, Chrome had 3 % of the io browser grocery store. [ 263 ]


On Linux distributions, back for 32-bit Intel processors ended in March 2016 although Chromium is even supported. [ 264 ] As of Chrome interpretation 26, Linux installations of the browser may be updated alone on systems that support GCC v4.6 and GTK v2.24 or late. frankincense deprecate systems include ( for example ) Debian 6 ‘s 2.20, and RHEL 6 ‘s 2.18. [ 265 ]


support for Google Chrome on Windows XP and Windows Vista ended in April 2016. The final turn of Google Chrome that can be run on Windows XP and Windows Vista was version 49.0.2623.112, [ 267 ] released on April 7, 2016, [ 268 ] then re-released on April 11, 2016. [ 269 ] support for Google Chrome on Windows 7 was supposed to end upon the announcement on July 15, 2021, [ 270 ] and abruptly moved to January 15, 2022, however due to the ongoing COVID-19 pandemic and enterprises are taking more clock to migrate to Windows 10 or 11, the end of corroborate date was pushed at least on January 15, 2023, receiving critical security and constancy updates of the Chrome browser. [ 271 ] “ Windows 8 mode ” was introduced in 2012 and has since been discontinued. It was provided to the developer distribution channel, which enabled Windows 8 and Windows 8.1 users to run Chrome with a full-screen, tablet-optimized interface, with access to photograph, sharing, and search functionalities. [ 272 ] In October 2013, Windows 8 manner on the developer distribution channel changed to use a background environment mimicking the interface of Chrome OS with a dedicated windowing organization and taskbar for network apps. [ 273 ] This was removed on version 49 and users that have upgraded to Windows 10 will lose this have. [ 274 ]


Google dropped corroborate for Mac OS X 10.5 with the free of Chrome 22. [ 275 ] Support for 32-bit versions of Chrome ended in November 2014 with the passing of Chrome 39.

Chrome OS

Google Chrome is the footing of Google ‘s Chrome OS operating arrangement that ships on specific hardware from Google ‘s manufacture partners. [ 278 ] The drug user interface has a minimalist blueprint resembling the Google Chrome browser. Chrome OS is aimed at users who spend most of their computer time on the Web ; the entirely applications on the devices are a browser incorporating a media actor and a file coach. [ 279 ] [ 280 ] [ 281 ] [ 282 ] [ 283 ] Google announced Chrome OS on July 7, 2009. [ 284 ]


Google Chrome was met with acclaim upon release. In 2008, Matthew Moore of The Daily Telegraph summarized the verdict of early reviewers : “ Google Chrome is attractive, fast and has some impressive newfangled features … ” [ 285 ] initially, Microsoft reportedly played down the threat from Chrome and predicted that most people would embrace Internet Explorer 8. Opera Software said that “ Chrome will strengthen the Web as the biggest lotion platform in the world ”. [ 286 ] But by February 25, 2010, BusinessWeek had reported that “ For the first time in years, energy and resources are being poured into browsers, the omnipresent programs for accessing message on the Web. recognition for this vogue – a boon to consumers – goes to two parties. The first gear is Google, whose big plans for the Chrome browser have shaken Microsoft out of its competitive torpor and forced the software giant to pay fresh attention to its own browser, Internet Explorer. Microsoft all but ceased efforts to enhance IE after it triumphed in the last browser war, sending Netscape to its doom. now it ‘s back in gear. ” [ 287 ] Mozilla said that Chrome ‘s introduction into the network browser marketplace comes as “ no real surprise ”, that “ Chrome is not aimed at competing with Firefox ”, and furthermore that it would not affect Google ‘s tax income relationship with Mozilla. [ 288 ] [ 289 ]

Chrome ‘s design bridges the gap between desktop and alleged “ cloud computer science. ” At the touch of a release, Chrome lets you make a desktop, Start menu, or QuickLaunch shortcut to any Web page or Web application, blurring the line between what ‘s on-line and what ‘s inside your personal computer. For exemplar, I created a background shortcut for Google Maps. When you create a shortcut for a Web application, Chrome strips away all of the toolbars and tabs from the window, leaving you with something that feels much more like a background application than like a Web application or page .PC World[290]

With its authority in the world wide web browser market, Google has been accused of using Chrome and Blink development to push new web standards that are proposed in-house by Google and subsequently implemented by its services first and foremost. These have led to performance disadvantages and compatibility issues with competing browsers, and in some cases, developers intentionally refusing to test their websites on any other browser than Chrome. [ 291 ] Tom Warren of The Verge went angstrom far as comparing Chrome to Internet Explorer 6, the default browser of Windows XP that was much targeted by competitors due to its like ubiquity in the early 2000s. [ 292 ] In 2019, Google similarly faced criticism over planned changes to its extensions API for Chrome ( dubbed “ Manifest V3 ” ), which would inhibit the potency of certain forms of ad blocking software by preventing the practice of the WebRequest API to block and modify network connections. Google intends extensions to transition to another API known as DeclarativeWebRequest, which allows the extension to set up pre-configured rules that are processed by the browser itself quite than through the extension. however, concerns over how well the API would perform, in combination with concerns over a cap on the number of entries that may be blacklisted, led to criticism that these changes were designed to inhibit ad jam ( citing Google ‘s vest pastime in the on-line advertise industry ). Google cited performance issues associated with WebRequest, as it requires all network traffic to go through the annex before the page is loaded, arsenic well as its use in malicious extensions, as justification for these changes. In June 2019, it announced that it would increase the aforesaid crown from 30,000 to 150,000 entries to help quell concerns. [ 293 ] [ 294 ] [ 295 ]


market share

[297] The most use web browser per country in 2020 Chrome overtake Firefox in November 2011, in global custom. As of March 2021, according to StatCounter, Google Chrome had 67 % worldwide background custom plowshare, making it the most widely used world wide web browser. [ 298 ] Along with Safari and Mozilla Firefox, Chrome receives a weekend “ find ”, which boosts its market share by equally much as three share points on weekends, at the expense of Internet Explorer. [ 299 ] It was reported by StatCounter, a web analytics company, that for the single day of Sunday, March 18, 2012, Chrome was the most use web browser in the world for the first time. Chrome secured 32.7 % of the ball-shaped network browsing on that sidereal day, while Internet Explorer followed closely behind with 32.5 %. [ 300 ] From May 14–21, 2012, Google Chrome was for the first gear time responsible for more Internet traffic than Microsoft ‘s Internet Explorer, which long had held its spot as the most practice vane browser in the global. [ 301 ] According to StatCounter, 31.88 % of web traffic was generated by Chrome for a nourish time period of one week and 31.47 % by Internet Explorer. Though Chrome had topped Internet Explorer for a one day ‘s custom in the by, this was the first clock time it had led for one full week. [ 302 ] At the 2012 Google I/O developers ‘ league, Google claimed that there were 310 million active users of Chrome, about double the total in 2011, which was stated as 160 million active users. [ 303 ] In June 2013, according to StatCounter, Chrome overtook Internet Explorer for the first base time in the US. [ 304 ] In August 2013, Chrome was used by 43 % of internet users worldwide. This survey was done by Statista, which besides noted that in North America, 36 % of people use Chrome, the lowest in the world. [ 305 ]
As of May 2020, Chrome is the most use browser in every country. [ 307 ]

enterprise deployment

In December 2010, Google announced that to make it easier for businesses to use Chrome they would provide an official Chrome MSI package. For business use it is helpful to have full-fledged MSI packages that can be customized via transform files ( .mst ) – but the MSI provided with Chrome is only a very limited MSI negligee fitted around the normal installer, and many businesses find that this arrangement does not meet their needs. [ 308 ] The normal downloaded Chrome installer puts the browser in the drug user ‘s local app data directory and provides invisible background updates, but the MSI software will allow facility at the organization level, providing system administrators control over the update process [ 309 ] – it was once possible entirely when Chrome was installed using Google Pack. Google besides created group policy objects to fine-tune the demeanor of Chrome in the business environment, for exemplar by setting automatic updates intervals, disabling auto-updates, and configuring a home page. [ 310 ] Until adaptation 24 the software is known not to be quick for enterprise deployments with roaming profiles or Terminal Server/Citrix environments. [ 311 ] In 2010, Google first started supporting Chrome in enterprise environments by providing an MSI wrapping around the Chrome installer. Google starting providing group policy objects, with more total each publish, [ 312 ] and today there are more than 500 policies available to control Chrome ‘s behavior in enterprise environments. [ 313 ] In 2016, Google launched Chrome Browser Enterprise Support, a paid overhaul enabling IT admins entree to Google experts to support their browser deployment. [ 314 ] In 2019, Google launched Chrome Browser Cloud Management, a dashboard that gives business information technology managers the ability to control contented handiness, app use and browser extensions installed on its deploy computers. [ 315 ]


In September 2008, Google released a big helping of Chrome ‘s source code as an open-source project called Chromium. This be active enabled third-party developers to study the underlying reservoir code and to help port the browser to the macOS and Linux operating systems. The Google-authored part of Chromium is released under the permissive BSD license. [ 316 ] other portions of the source code are subject to a variety show of open-source licenses. [ 317 ] Chromium is alike to Chrome, but lacks built-in automatic updates and a built-in Flash actor, angstrom well as Google stigmatize and has a blue-colored logo alternatively of the motley Google logo. [ 318 ] [ 319 ] chromium does not implement exploiter RLZ tracking. [ 174 ] [ 169 ] [ 320 ] Initially, the Google Chrome PDF viewer, PDFium, was excluded from Chromium, but was belated made open-source in May 2014. [ 321 ] [ 322 ] PDFium can be used to fill PDF forms. [ 323 ]

Developing for Chrome

It is possible to develop applications, extensions, and themes for Chrome. They are zipped in a .crx file and contain a manifest.json charge that specifies basic information ( such as adaptation, name, description, privileges, etc. ), and other files for the drug user interface ( icons, popups, and so forth ). Google has an official developer ‘s guide on how to create, develop, and print projects. [ 324 ] Chrome has its own web shop where users and developers can upload and download these applications and extensions. [ 325 ]

imposture by malware

As with Microsoft Internet Explorer, the popularity of Google Chrome has led to the appearance of malware abusing its list. In late 2015, an adware replica of Chrome named “ eFast ” appeared, which would usurp the Google Chrome initiation and hijack file type associations to make shortcuts for park file types and communication protocols link to itself, and interject advertisements into vane pages. Its similar-looking icon was intended to deceive users. [ 326 ] [ 327 ] [ 328 ]
