In a Nov. 29 blog post, Chris Peterson, developer on Mozilla's Firefox for Android team, said Web developers have been using Adobe Flash to play H.264 video on Firefox for Android, but Adobe no longer supports Flash for Android. Thus, Mozilla needed a new solution, so Firefox now uses Android’s “Stagefright” library to access hardware video decoders, Peterson said.
Firefox currently supports H.264 playback on any device running Android 4.1 (Jelly Bean) and any Samsung device running Android 4.0 (Ice Cream Sandwich), he said. “We have temporarily blocked non-Samsung devices running Ice Cream Sandwich until we can fix or workaround some bugs,” Peterson said. Support for Gingerbread and Honeycomb devices is planned for a later release, he added.
To test whether Firefox supports H.264 on your device, try playing this “Big Buck Bunny” video.
For users whose devices are not yet supported, Peterson said:
“If your device is not supported yet, you can manually enable H.264 for testing. Enter
in Firefox for Android’s address bar, then search for ‘stagefright.’ Toggle the ‘stagefright.force-enabled’ preference to
. H.264 should work on most Ice Cream Sandwich devices, but Gingerbread and Honeycomb devices will probably crash.”
Moreover, Firefox Beta can disable insecure content on HTTPS secure Websites to maintain the privacy of users’ communication with the Website. This feature can be enabled in about:config.
