Firefox for Android is a web browser developed by Mozilla for Android smartphones and tablet computers. As with its desktop version, it uses the Gecko layout engine, and supports features such as synchronization with Firefox Sync, and add-ons.
The initial version of Firefox for Android was codenamed Fennec and branded Firefox for mobile; it initially supported Maemo and Android before supporting MeeGo and Firefox OS as well. Support for Maemo was later dropped. In 2020, a redesigned version of Firefox for Android (codenamed Fenix, and also branded as Firefox Daylight) was released, which introduced a new internal architecture and user interface inspired by Firefox Focus, new privacy features, and switching to curated WebExtensions for add-ons.
