[ubuntu] Fullscreen Youtube in Firefox Crashing

view story

http://ubuntuforums.org – Hey guys, so this has been going on for a long time but I am actually determined to fix it now...Basically, ever since upgrading to 12.04 LTS, watching fullscreen youtube videos (often in 720p or 1080p) will eventually crash Firefox/Flash and the workspace will just be frozen... Audio will still work, but I basically have to switch workspaces, kill the firefox and plugin process, and then relaunch firefox. Sometimes happens in under 10 seconds after making the video fullscreen, sometimes 1-2 minutes. Using the latest firefox (14.0.1?) and flash. Anyone have any ideas/suggestions? Anyone else (Hardware)
