Comment 48 for bug 85627

I have this same issue when I play more than one video or try to navigate away from a video that is playing.

I have the following plugins

adblock plus
stumbleupon
password exporter
chatzilla

This happens every time so if you can tell me how to save the crash info I would be happy to help. I also run Beryl and the firefox screen greys out and I have to force a close (it doesn't crash and go away).
