Firefox forgets stuff - cheddar
Whenever anyone has an IE problem the first response is 'get Firefox' or 'Opera is best', so I am going to say - get Internet Explorer it works fine!

Sorry, cant help beyond that though couldn't resist!
Firefox forgets stuff - adverse camber
well im on ff same version. I dont have your main problem, but something that has crept in recently is the hanging - at which point I have to look for the pop up window whih is trying to initiate a dial up connection rather than the broadband.

I havent spent much time looking at it but a quick google suggested that one of the m$ updates introduced a dns lookup problem. that results in a polluted dns cache.
