Firefox for iOS is a browser from Mozilla, for the Apple iPhone, iPad and iPod Touch mobile devices.[5] It is the first Firefox branded browser not to use the Gecko layout engine as is used in Firefox for desktop and mobile. Due to iOS security restrictions chosen by Apple (specifically the inability to set writable pages executable, which is essential for just-in-time compilation), Firefox has to use the built-in iOS WebKit-based rendering framework instead of Gecko.[6] Firefox for iOS supports Firefox Sync and is able to sync Firefox's browsing history, bookmarks, and recent tabs.


In December 2014, Mozilla announced it was designing a version of Firefox for iOS.[7] In September 2015, it released a limited preview of the app available only in the New Zealand iOS App Store.[8] In November 2016, Firefox Focus, a stripped down version of the full browser with a specific focus on incognito browsing, was published in the Apple App Store.[9]

Version 9.0, released in September 2017, introduced tracking protection on iOS 11 (and later).[10]

Version 10.0, released in November 2017, introduced a redesigned user interface, corresponding to the new "Photon" UI introduced with Firefox 57 later that month.[11]

Firefox Home was a previous project for a companion app for the iPhone and iPod Touch based on the Firefox Sync technology. It allowed users of either device to access their Firefox browsing history, bookmarks, and recent tabs. It also included Firefox's "Awesomebar" location bar. Firefox Home is not a browser; the application launches pages in either a Webkit Web viewer or in Safari.[12][13] Mozilla pulled Firefox Home from the App Store in September 2012, stating it would focus its resources on other projects. The company subsequently released the source code of Firefox Home's underlying synchronization software.[14]


Firefox for iOS supports many features common to other mobile browsers, including tabs, history, and bookmarks. It also implements some unique features, including the same tracking protection as found in Firefox Focus, a new tab page mimicking that found on other versions of Firefox, and support for syncing with a Firefox account between devices.

Unlike Firefox on Android, Firefox for iOS does not support browser add-ons. Additionally, it uses Apple's Webkit rendering engine, rather than Mozilla's Gecko. Both of these limitations are in accordance with Apple's rules for submitting apps to the App Store.
