Hi Vassilis, The problem seems to have dissapeared with an apt update/upgrade. Unfortunately I don't know which package upgrade (could have been Firefox itself) resolved the issue.
This was a clean install of Dapper. Yes, I kept my old home directory and presumed this was related. I created news users from scratch and for a while was convinced the freezing went away when logged in as those users. That was premature celebration - firefox still froze. I will check if those other 'users' still freeze Firefox, but if not I have to assume it really did dissapear with an update. Strangely no other users reported this issue.
