Thank you for the bug report. Could you please install firefox-dbg (these are the firefox debugging symbols) and try to obtain a backtrace (or crash report) by following the instructions on https://wiki.ubuntu.com/MozillaTeam/Bugs This will greatly aid us in tracking down your problem.
It is of particular interest that you run apport-retrace -d against your crash report before uploading. Which flash package do you have installed? Which Java package do you have installed? Which firefox extensions do you have installed? -- it crashed all of a sudden. https://launchpad.net/bugs/71436 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
