Firefox3.6(windows 7) and fadein

Hello, I am working on a site www.georgiebeauty.com. In firefox everything set to fade in receives a terrible neon outline while fading. This does not happen in OSX or with chrome. 

IE7 and 8 have all kinds of problems with the fade in. I am mostly concerned with firefox.

I am running supersize.core(a plugin) for my background.

Any ideas? I read something about IE7 and fonts not displaying properly after a fadein, is this related?
