One thing we are doing here at Red Hat Brno is maintain Firefox for Fedora and RHEL. The job is mostly focused on making sure we have Firefox available on all RHEL versions with all the latest security fixes, but it also gives our great team of Martin Stransky and Jan Horak some time to work on adding new features to Firefox to make sure it feels like a more integrated part of your desktop. They are currently working on 3 such features that you will hopefully be able to enjoy soon. The first is a patch to inhibit the screensaver when you are watching HTML5 or Flash content fullscreen. So if you are annoyed by having to move your mouse every 3 minutes to avoid the screen dimming when watching The Daily Show this is the fix for you. The second item they are working on is enabling the GStreamer backend in Firefox on Fedora. Which means that if you install for instance H264 support for Totem you will also have H264 support for HTML5 in Firefox. And finally there is also ongoing work on adding support for GIO in Firefox to make sure that any setup that works with GIO in terms of remote file access also works with Firefox, this latest task is taking some time though as it is currently blocking on some code refactoring in Firefox.
