I can confirm as well. it's not just firefox - I use the web developer toolbar and have it open up source code in Gedit (which I assume then becomes a separate process?). Gedit also crashes the system in the exact same way. I resorted to gedit as View-Source was causing this issue every time.
Only occurs with Nvidia drivers installed. Nothing new, or helpful I guess, I'm only adding this comment so I can stay informed with changes to this bug report. -- Page crashes X https://launchpad.net/bugs/46034 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
