Mozilla Firefox is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Firefox is available for Windows, macOS, Linux, and BSD operating systems. Its mobile versions are available for Android, and Firefox OS; the latter was discontinued in 2016.

Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface.

Firefox was created in 2002, under the name "Phoenix" by the Mozilla community members who desired a standalone browser, rather than the Mozilla 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, and challenged Internet Explorer's dominance with 60 million downloads within nine months.

Firefox usage grew to a peak of 32.21% at the end of 2009, with version 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 January 2019, Firefox has 9.5% usage share as a "desktop" browser, according to StatCounter, making it the second-most popular such web browser after Google Chrome.
