Thanks for reporting this bug to help make firefox and Ubuntu better!
Here are a few things to try to help diagnose this issue.
1) Are you using any plugins or extensions? If so try creating a new
profile and see if the bug persists.
To do this start firefox with: firefox -ProfileManager
Be careful not to delete your profile. It can erase the whole directory that
the profile is saved in!
Make a new profile, see if the bug remains.
2) Start Firefox fromteh terminal
Enter: firefox in a terminal
Please upload the output of running this command. Also provide any output at
the time of the crash, if you can see it.
3) Install debugging packages run:
# sudo apt-get install firefox-dbg \
libgtk2.0-0-dbg \
libnss3-0d-dbg \
libnspr4-0d-dbg \
libpango1.0-0-dbg \
libc6-dbg
4) After closing all instances of Firefox, start Firefox from the terminal with
the following command:
firefox -g 2>&1 | tee ~/Desktop/gdb-firefox.log
... # some output
(gdb) run
... # run and reproduce crash
(gdb) bt full
... # full backtrace output
(gdb) thread apply all backtrace full
... # all threads full backtrace output
(gdb) quit
Now ~/Desktop/gdb-firefox.log will contain infos we need to initially
process your crash bug. So, please attach that file to your bug report.
5) Copy and paste in a xterm the following command:
TMPDIR=$(mktemp -d)
apport-unpack /var/crash/_usr_lib_firefox_firefox-bin.1000.crash $TMPDIR
gdb -nx /usr/lib/firefox/firefox-bin -core $TMPDIR/CoreDump -ex 'backtrace
full' -ex 'thread apply all backtrace full' -ex 'quit' 2>&1 | tee gdb.log
rm -fr $TMPDIR
That command will run gdb against the coredump file included in the
crash report that was generated when firefox crashed.
Upload the resulting gdb.log to launchpad.
One good thing to do is looking at the gdb output and search for missing
dbg libraries or other warnings, install them and run again gdb.
With this additional information, the devs should be able to help with
this bug.
