I was forwarded an email about this and felt I should post it on here.

I have talked with forum admin Heyallo about this. He informs me that Firefox Version 3.5.4 "apparently" fixes this problem, but also that 3.6 is expected to be out shortly.
Another option to this would be to try a broswer called Seamonkey which is based off the old Mozilla broswer code before they started developing Firefox.
