Makes Hotmail hang - error box with option to stop script, continue or debug.

I have updated or reinstalled, Firefox, Java and everything else I can think of. Cleared cookies, cache and everything else I can think of.

I've been a Hotmail customer for over a decade and didn't want to give up my Hotmail address. But this is just about the final straw. I've spent two days now trying to fix this and if someone here doesn't have some kind of answer I will just move to Gmail.

Cheers
