If I recall correctly, I did forcefully shutdown the X server before the crash, and the crash occurred when I attempted to start Firefox afterward.
That said, I've been completely unable to reproduce the crash since that time with that version of Firefox, despite my best efforts to do so. -- Firefox crash report https://launchpad.net/bugs/69147 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
