Firefox for Android (codenamed Fennec) is the build of the Mozilla Firefox web browser for devices such as smartphones and tablet computers. Mozilla makes another mobile browser called Firefox for iOS, and for a while, Firefox for Android had a different name, and supported more than just the Android operating system.

Firefox for Android uses the same Gecko layout engine as Mozilla Firefox. For example, version 1.0 used the same engine as Firefox 3.6, and the following release, 4.0, shared core code with Firefox 4.0. Its features include HTML5 support, Firefox Sync, add-ons support and tabbed browsing.

The codename used for Firefox for Android is Fennec. It comes from the fennec fox, a small desert fox (just as the Fennec browser is a small version of Firefox browser). Firefox for Maemo Beta 5, released in 2009, was the first release to have official Firefox branding, with Firefox name and logo.

Plugin support was initially disabled by default, removing compatibility with popular web content types such as Adobe Flash. In September 2011, Flash support was implemented in pre-release builds for pre-Honeycomb versions of Android. Flash support for 4.x has been enabled for most smartphones in version 14.0.

The browser's version numbering was bumped from version 2.0 to version 4.0 to more closely match desktop releases of Firefox since the rendering engines used in both browsers are the same.
