The former Firefox for Android (codenamed Fennec), was a web browser for Android devices, such as mobile phones and tablets. Its user interface was optimized for small screens and tablets. It included the Awesome Bar, tabbed browsing, add-on support, a password manager, location-aware browsing, and the ability to synchronize with the user's other devices with Firefox Browser using Firefox Sync. It was criticized for being slow, however, in part due to its poor port of Gecko. At the end of its existence, it had a marketshare of 0.5% on Android.
