Description of problem: html5 audio and video work only for the first user that plays audio or video in firefox. It's upstream bug 612246, https://bugzilla.mozilla.org/show_bug.cgi?id=612246. From comment 5 there: strace -fFeopen reveals whats going on here: open("/tmp/mozilla-media-cache/media_cache", O_WRONLY|O_CREAT|O_EXCL|O_TRUNC, 0700) = -1 EACCES (Permission denied) The reason for this failure is obvious: I have another FF instance running under a different user/group which created /tmp/mozilla-media-cache with permissions 0700. This precludes any new FF instance from opening the cache file. There is a patch available there. Version-Release number of selected component (if applicable): firefox-7.0.1-1.fc15.x86_64 but f16beta has the same bug How reproducible: always Steps to Reproduce: 1. create two user accounts 2. open firefox in one and play http://upload.wikimedia.org/wikipedia/commons/a/a9/Tromboon-sample.ogg 3. open the other account and play same url Actual results: no playback Expected results: play
