I also have this issue. Happens very frequently when streaming audio from a website. Also, when it crashes, it does not give a "report" option. So, I guess Mozilla is not aware of this problem. HELP.

Yeah, I've been having this issue too. It wouldn't be such a bother if all it was was a simple refresh away, but with that god damn poorly coded plugin container in tow it causes my computer to drag it's feet so bad that it nearly crashes the whole damn thing. I'll give them a little time to fix it, but Chrome is looking nicer and nicer all the time.
