Several times since upgrading to Firefox 3.5, it's just
disappeared. I
can't find a reliable pattern to it. When it goes, gnome panel goes
away, too. After a few seconds, gnome panel returns.
1. yum install firefox-debuginfo
2. Start firefox
3. Use ps to find its pid
4. ssh into this machine from another host
5. gdb /usr/lib/firefox-3.5/firefox <PID>
6. Wait for firefox to crash
7. Hopefully, gdb will be able to catch the signal
8. Post the backtrace of every thread into Bugzilla
