YouTube (720 HD or Fullscreen) causes Firefox to crash
Playing videos on YouTube in 720HD or in fullscreen mode causes an immediate Firefox crash. I've tried in Safe Mode and the same things cause a Firefox crash. I've gone through the steps on the Mozilla support page to try and troubleshoot the crash, and none of the steps there have resolved the crashing problem with YouTube. Angieslist.com also recently caused a Firefox crash.

Thank you for the reply. Unfortunately, those suggestions did not address the problem I'm having with Firefox crashing. I'd already made sure that Flash was up to date, so I'm hoping you have a different suggestion to help fix this problem. I'm going to have to abandon Firefox for Safari or Chrome (neither of which has the crashing problem I'm experiencing with Firefox) if we can't get this resolved, and I'd much prefer to keep using Firefox. Thanks in advance for looking at this again.
