I use Firefox, and sometimes ahve difficulty loading the AB site. I get the topic list down the L?H side, but not shaded or anything, and the my profile / sign out is in the centre, but not 'active' eg I can't click on anything. It seems to work OK when I use Internet Explorer, but IE is soo sloow!
It is not the AB that is at fault as the exact same thing used to happen to me when I used firefox. The only reason it loads quicker is because it doesn't load all the images, and because I like a larger text size the text used to overlap and it all became too confusing with firefox and the same thing happened with ebay.
I couldn't get on with firefox and have now switched to the Opera browser and it is brilliant much better than firefox and IE. It does everything I want it to do. Try Opera you will love it. I promise
Opera is definitely very good now. Personally I don't see it as being as good as firefox, basically because of the fact that firefox is free software, and it's got a good extensions system.
I browse AB with firefox almost daily, and have had no problems at all for months.
