Thanks for your 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/DebuggingFirefox . This will greatly aid us in tracking down your problem.
You may also be able to do the following: sudo apt-get install firefox-dbg apport-retrace -d /var/crash/_usr_lib_firefox_firefox-bin.1000.crash and upload a reduced report which will hopefully contain the information needed. ** Changed in: firefox (Ubuntu) Status: Unconfirmed => Needs Info -- /var/crash/_usr_lib_firefox_firefox-bin.1000.crash https://launchpad.net/bugs/77423 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
