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?

We NEED the debugging symbols so please follwo the directions on the link i supported you with. -- 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
