I've only just installed Firefox after recently having aol issues for the first time since dial up. No problems at all so far (touch wood!) except I didn't realise I had to unblock popups so I could view profiles from the chatrooms. Not that I'm a perv or owt ...
who's your ISP? it's not AOL is it? as fer Firefox problems, yeah i'm having loads. it's dead slow and thoroughly crap, with shedloads of 100 meg plus memory leaks, and none of that blistering page rendering ever since they brought out version 2, and half me most essential extensions don't work properly either? n x x x ;)
