Firefox was released on November 9, 2004, and challenged Internet Explorer's dominance with 60 million downloads within nine months. 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 is also available for Android and iOS, however the iOS version uses the WebKit layout engine instead of Gecko due to platform limitations, as with all other iOS web browsers.įirefox was created in 2002 under the codename "Phoenix" by the Mozilla community members who desired a standalone browser, rather than the Mozilla Application Suite bundle. 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, NetBSD, illumos and Solaris Unix. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.

Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. Mozilla Firefox, Firefox Browser, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, Mozilla Corporation.
