Mozilla Firefox (or simply Firefox) is a free and open-sourceweb browser developed by the Mozilla Foundation and its subsidiary the Mozilla Corporation. Firefox is available for Windows, macOS and Linux operating systems, with its Firefox for Android available for Android (formerly Firefox for mobile, it also ran on the discontinued Firefox OS), and uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. An additional version, Firefox for iOS, was released in late 2015, but this version does not use Gecko due to Apple's restrictions limiting third-party web browsers to the WebKit-based layout engine built into iOS.
Firefox was created in 2002 under the name "Phoenix" by Mozilla community members who desired a standalone browser, rather than the Mozilla Application Suite bundle. Even 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 in November 2004, and was highly successful with 60 million downloads within nine months, which was the first time that Internet Explorer's dominance was challenged. Firefox is considered the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998 before their acquisition by AOL.
