Sorry, was too lazy to go into specifics.
When I say it doesn't load properly, it's because it seems to load everything fine, but when I mouse over something for whatever reason, it creates and identical copy of it(be it text, images, buttons) and puts it halfway below and behind the original. So it looks like an ugly shadow. Problem is, if I want to click it, I have to click the "shadow". Very annoying but I put up it with because "select all" seems to get rid of it.
The problem seems to decrease the longer Firefox has been on and I was about to say that I don't see it anymore when I realised that it had made Zorro's message go all funny. I think it's got something to do with caching the page, just a guess.
I installed over Firefox 2.
PS: Anybody else find the OSX version of Firefox 3 really ugly? I'm using the GrApple skin instead.
