I've Got A Firefox/Font Issue

I think the image is quite explanatory of the basic situation. Any idea what the hell I should do? :\

hold ctrl and scroll your mouse wheel up?

Yeah, the screenshot is deceiving, imageshack resized it. Here's (hopefully) a clearer image. It's the font specifically that's messed up.
Edit: ricky on IRC suggested renewing my Firefox profile, that didn't work either.
Re-edit: For what it's worth, my Opera loads www.google.com crappy, and IE not at all, I don't know if it's related to the text issue or not.Another Edit: Problem solved! After trying a bunch of things, I eventually checked Arial properties in windows\fonts\ to have it tell me "Windows cannot find 'C:\Program Files\BestGameEver\Audiosurd\engine\Cache\Fonts\Arial.ttf'. Make sure you typed the name correctly, and then try again. To search for a file bla bla". I deleted my system Arial, placed in Arial.ttf from my Audiosurf cache and tada, problem fixed. What happened is that I renamed C:\Program Files\BestGameEver\Audiosurf to C:\Program Files\Audiosurf\Audiosurf because "BestGameEver" is a bitch of a folder name when looking for a game folder.tl;dr: Fuck audiosurf with a hot metal rod.Thanks for the help on here and IRC.
