Silly question but what happens if you run firefox from a terminal, do 
you get any errors in the terminal? (+ quitting the terminal SHOULD kill 
f-f if it freezes)

Also did you install Ubuntu Gnome or did you put Gnome on top of another 
Ubuntu? if so the firefox-Ubuntu-compatability layer or whetevr it's 
called these days (the thingy that makes it work with Unity) MIGHT be 
causing a conflict in Gnome?

Also a silly point to raise here (I'm sure I'll be shot down in flames 
if I am incorrect) but does Gnome Fallback still exist, I am almost 
certain that I've seen a discussion about the removal of the fallback 
option. (personally I don't like the new Gnome but thats just me)

If the only issue is f-fox I am certain the need to re-install will NOT 
be necessary, however back up your passwords (if you save them) and your 
bookmarks (really easy to do from in f-f but MUST be a file somewhere!)

Happy hunting
