Public bug reported: I can confirm the problem described by someone else here:
http://askubuntu.com/questions/173732/firefox-keeps-crashing-repeatedly Note the possibly relevant log message on that page. Firefox crashes on startup if both the globalmenu add-on and firebug are both installed. Removing one or the other fixes the problem. I suggest this is a problem with the globalmenu extension rather than firebug, because firebug used to work fine in Firefox 13.
