I've got FireFox installed, though I prefer using IE. I never had any problems with it and I'm used to it's interface.
To get back on topic: If I use the light blue stylesheet, the moderators listed on the bottom of each subforum are only readable if highlighted, same goes for the 'previous topic' 'index' and 'next topic' links on the bottom of a topic. All that's visible is the little arrows next to the links, maybe it's because of my settings, but I've tested it in both IE and FF(take that Ube

) and they both display it the same way.
