Sorry, I have no idea in that case. I recently switched to Mandriva and FF 3.5.5 is working fine there.

I suggest you ask in the Ubuntu forums. You might also try another distro on a live CD and see if you get the same problem.

It might just be something as simple as a FF setting. Are you sure you have not managed to turn off Javascript somewhere?

Do other browsers work OK? If Epiphany Gecko is still in the repos trying it might narrow down the possibilities because it uses the same rendering engine as FF (they may have switched completely to the newer webkit based version of Epiphany). I think it has its own copy (rather than using a shared library), but if it also does not work it is a clue.
