I've been having trouble for about two weeks now, it seems to be about the time you guys switched to .com from .co.uk - or perhaps I just noticed it when things started going a little wrong. It is true that it is mainly a Firefox issue, although I've had a little trouble with Safari too. A lot of the review pages will return error messages. If I go back and try the link again it will often work on the second or third try. Same thing with the forums, they were just not accessible at all for about two days last week in Firefox. In the last 48 hours or so, I haven't had any problems however, so it seems to be fixed. I did clear my cache last week to no avail, but whatever it was its rectified - at least from my computer (Mac OS X.5.7 if it matters).
