MMm... seems to be the Tab History add-on that b0rked it. With that disabled, FF4 at least functions.
But I absolutely require Tab History functionality.. time to go hunting..

EDIT: Mmm.. something in there is giving me Tab History functionality already, without the add-on. So that one's good.

Now to check out the other missing add-ons.
