Firefox 10 keeps crashing

After upgrading to Firefox 10, the new version kept crashing every time I opened it. Running it in safe mode (firefox -safe-mode) didn't help.

I ended up creating a new profile to fix this problem using the following command and switch:-

firefox -P

All plugins were gone and needed reinstalling. I could get some data back though from the old profile folder in

/home/tom/.mozilla/firefox/xxxx.default
