I am having a problem checking my gmail account while useing firefox 1.5 and 1.0.7. The page will say " loading" , but that is all it does. I get a done message in the bottom bar of the browser however , it is not

This problem just started 2 days ago. I first noticed it from work ( broadband, xp sp2, firefox is default browser)
then I checked from home (dial-up , xp sp2, ie default browser).
I believe it is a secure site issue , some setting somewhere, I don't understand why it would happen suddenly on two different pc's. I think maybe something changed with the gmail site but have found no info as of yet. I was wondering if any of you have any ideas.
Thanks in advance....
