Comment 33 for bug 71913

New Note 5

I can confirm a similar problem - I'm not sure if this is the same bug as described here, but here goes - firefox has been completely crashing my computer since I upgraded from Feisty to Gutsy a week or so ago (i.e. I can't switch VTs to find out what's going on, can't reset Xorg using Ctrl+Alt+Backspace - I have to Alt+SysReq+B to reboot my computer. I've noticed it most whenever I've been writing into text boxes (e.g. gmail) - which makes it even more frustrating!

I have the flash plugin installed from the official repos, and my Xorg.conf is the default configuration, albeit with the VNC module loaded, and I'm running the latest Gutsy in dual head mode (ATI card - so using xrandr).
I have reproduced the crash using two different firefox profiles - my main one with a handful of extensions, and a basic profile with no extensions at all - so I think we can rule profiles out.

I have a crash log I found in /var/crash which I've submitted, and gedit-ing it seems to bring my computer grinding to a halt - and so far I can't find any mention of a backtrace like what some of you have included: The only mention is:
Stacktrace: #0 0xffffe410 in ?? ()
StacktraceTop: ?? ()
And is it also worth mentioning that it also says that firefox-bin crashed with SIGSEGV?

Does any of this information seem familiar to anyone else?
