I'm using 3G's dongle to access the internet. Recently, I have been having trouble accessing my hotmail account. I can sign in but can get no further and I am left with a blank screen. This happens on Safari 3 and Firefox.

I have cleared out my cache and increase the cache's memory but the only way to resolve the problem is to re-start my iBook G4 and most times this doesn't sort out the problem.

Has anyone else had this trouble? 3G have been of no help.

Recently I used my Mac at a friend's house who had wireless access and had no trouble. Is it something to do with Firefox being upgraded?

thanks
