I'll think through an automated solution, but in the meantime here is a
manual one....

If the user's firefox process dies a sudden death, it can leave a stale
lock file around. If the user has no running firefox-bin processes (I'm
pretty sure "pkill -u <user's uid>  firefox-bin" would do the trick),
you can safely remove the lock file:

	rm ~username/.mozilla/firefox/*/lock
