open-in-new
<p>Firefox for Android is a <a href="/facts/Web_browser/2pfyymLs">web browser</a> developed by <a href="/facts/Mozilla/FevL9Itn">Mozilla</a> for <a href="/facts/Android_(operating_system)/nNyHb0xz">Android</a> <a href="/facts/Smartphone/cSIrBMWG">smartphones</a> and <a href="/facts/Tablet_computer/6pGX2I7b">tablet computers</a>. As with its <a href="/facts/Firefox/xez2zv8H">desktop version</a>, it uses the <a href="/facts/Gecko_(software)/HXINMkgW">Gecko</a> <a href="/facts/Browser_engine/wLna3ate">layout engine</a>, and supports features such as <a href="/facts/Browser_synchronization/YnLvJypQ">synchronization</a> with <a href="/facts/Firefox_Sync/e7uJdEjU">Firefox Sync</a>, and <a href="/facts/Add-on_(Mozilla)/F0A6ctBz">add-ons.</a> </p><p>The initial version of Firefox for Android was codenamed Fennec and branded Firefox for mobile; it initially supported <a href="/facts/Maemo/gQyp5ehf">Maemo</a> and Android before supporting <a href="/facts/MeeGo/3P3HSE8K">MeeGo</a> and <a href="/facts/Firefox_OS/pBLG4suy">Firefox OS</a> 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 <a href="/facts/Firefox_Focus/CCnY7HtJ">Firefox Focus</a>, new privacy features, and switching to curated <a href="/facts/Features_of_Firefox/htfHKkec">WebExtensions</a> for add-ons. </p>
