Firefox Browser, also known as Mozilla Firefox 40 or simply Firefox, is a free and open-source[22] web browser developed by the Mozilla Firefox 40 Foundation and its subsidiary, the Mozilla Corporation. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.[23] In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.

Firefox is officially available for Windows 7 or newer, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems including FreeBSD,OpenBSD,[8] NetBSD,[9] illumos,[10] and Solaris Unix.[12] Firefox is also available for Android and iOS. However, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements, as with all other iOS web browsers. An optimized version of Firefox is also available on the Amazon Fire TV, as one of the two main browsers available with Amazon’s Silk Browser.

Firefox was created in 2002 under the codename “Phoenix” by the Mozilla Firefox 40 community members who desired a standalone browser, rather than the Mozilla Firefox 40 Application Suite bundle. During its beta phase, Firefox proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft’s then-dominant Internet Explorer 6. Firefox was released on November 9, 2004,[26] and challenged Internet Explorer’s dominance with 60 million downloads within nine months. Firefox is the spiritual successor of Netscape Navigator, as theMozilla Firefox 40 community was created by Netscape in 1998 before their acquisition by AOL.

Firefox usage grew to a peak of 32.21% at the end of 2009,[29] with Firefox 3.5 overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole. Usage then declined in competition with Google Chrome. As of May 2021, according to StatCounter, Firefox has 7.79% usage share as a “desktop” web browser, making it the fourth-most popular web browser after Google Chrome (67.53%) and Safari (9.86%) and Microsoft Edge (7.96%), or arguably even with Edge,[32] while its usage share across all platforms is lower at 3.59% still slightly ahead of Edge by same amount, enough for third place (after Google Chrome with 64.47% and Safari with 18.69%).

Mac OS

The first official release (Firefox version 1.0) supported macOS (then called Mac OS X) on the PowerPC architecture. Mac OS X builds for the IA-32 architecture became available via a universal binary which debuted with Firefox in 2006.[citation needed]

Starting with version 4.0, Firefox was released for the x64 architecture to which macOS had migrated.[161] Version 4.0 also dropped support for PowerPC architecture, although other projects continued development of a PowerPC version of Firefox.[162]

Firefox was originally released for Mac OS X 10.0 and higher.[163] The minimum OS then increased to Mac OS X 10.2 in Firefox 1.5 and 10.4 in Firefox 3.[164][165] Firefox 4 dropped support for Mac OS X 10.4 and PowerPC Macs, and Firefox 17 dropped support for Mac OS X 10.5 entirely. The system requirements were left unchanged until 2016, when Firefox 49 dropped support for Mac OS X 10.6–10.8. Most recently,Mozilla Firefox 40 ended support for OS X 10.9–10.11 in Firefox 79, with those users being supported on the Firefox 78 ESR branch until July 2021.


Since its inception, Firefox for Linux supported the 32-bit memory architecture of the IA-32 instruction set. 64-bit builds were introduced in the 4.0 release.[161] The 46.0 release replaced GTK+ 2.18 with 3.4 as a system requirement on Linux and other systems running X.Org.[173] Starting with 53.0, the 32-bit builds require the SSE2 instruction set. Firefox also can run on number of other architectures on Linux, including ARM, AArch64, PowerPC, POWER, Sparc, HPPA, MIPS, s390, and in the past Alpha, IA-64 (Intel Itanium) and m68k.

Firefox for Mobile

Firefox for mobile is a web browser for mobile phones, tablets, and PDAs. It was originally first released for the Nokia Maemo operating system, specifically the Nokia N900, on January 28, 2010. On March 29, 2011, an Android version was released, being based on version 4.[175] With the release of the mobile version, the browser’s version number was bumped from 2 to 4, synchronizing it with all future desktop releases of Firefox because the rendering engines used in both browsers are the same. Version 7 was the last release for Maemo on the N900.
The former Firefox for Android (codenamed Fennec), was a web browser for Android devices, such as mobile phones and tablets. Its user interface was optimized for small screens and tablets. It included the Awesome Bar, tabbed browsing, add-on support, a password manager, location-aware browsing, and the ability to synchronize with the user’s other devices with Firefox Browser using Firefox Sync. It was criticized for being slow,[179] however, in part due to its poor port of Gecko.[180] At the end of its existence, it had a marketshare of 0.5% on Android.
In April 2013, then-Mozilla Firefox 40 CEO Gary Kovacs said that Firefox would not come to iOS if Apple required the use of the WebKit layout engine to do so. One reason given by Mozilla was that prior to iOS 8, Apple had supplied third-party browsers with an inferior version of their JavaScript engine which hobbled their performance, making it impossible to match Safari’s JavaScript performance on the iOS platform.[182] Apple later opened their “Nitro” JavaScript engine to third-party browsers.[183] In 2015, Mozilla announced it was moving forward with Firefox for iOS, with a preview release made available in New Zealand in September of that year. It fully released in November later that year.[187] In November 2016, Firefox released a new iOS app titled Firefox Focus, a private web browser.
In August 2020, Mozilla Firefox 40  launched a new version of its Firefox for Android app, named Firefox Daylight to the public[189] and codenamed Fenix,[190] after a little over a year of testing.[180] It boasted higher speeds with its new GeckoView engine, which is described as being “the only independent web engine browser available on Android”. It also added Enhanced Tracking Protection 2.0, a feature that blocks many known trackers on the Internet.[191] It also added the ability to place the address bar on the bottom, and a new Collections feature. However, it was criticized for only having nine Add-ons at launch, and missing certain features In response, Mozilla Firefox 40 stated that they will allow more Add-ons with time.
