There is an existing old Bug #412647 . Not sure if this would be considered a dupe of the old one, as this is just specifically asking for a build option change. but fixing this would fix #412647.
there is also useful discussion at http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=682917 and https://bugzilla.redhat.com/show_bug.cgi?id=843583 including some reports of regressions with the gstreamer build. ** Bug watch added: Debian Bug tracker #682917 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=682917 ** Bug watch added: Red Hat Bugzilla #843583 https://bugzilla.redhat.com/show_bug.cgi?id=843583 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1051559 Title: Build Firefox with GStreamer support Status in The Mozilla Firefox Browser: Confirmed Status in “firefox” package in Ubuntu: Triaged Bug description: Building Firefox with GStreamer support would provide support for a lot of websites that use h264.
