Comment 12 for bug 91334

Binary package hint: firefox

Description of the problem:
After watching four or five getamac adverts on the apple website I tried to quit firefox and while the "are you sure you want to close the tabs" dialog was appearing firefox crashed.

Steps to reproduce:
1. Start firefox .
2. Visit
http://www.apple.com/getamac/ads/
3. Let the video play for a few seconds.
4. While that video is playing click on another video that you have yet to watch at the bottom of the screen.
5. Go to step 3 a few times.
6. Open another tab and try and quit firefox by using the X at the top right hand corner of the window.

Expected results:
Newly clicked videos to always keep playing. Firefox to quit without crashing.

Actual result:
Eventually the video area will be perpetually black. Quitting firefox results in a a crash.

How reproducible is the problem:
Haven't tried to reproduce it yet.
