links not working in firefox

hey /prog/,
I have a problem: my site www.matthaspictures.com dosent work in firefox. well, everything works except for the links in the tabs. they turn into plain old text and i dont know why. it works perfectly in IE, but has the same problem in safari.

I didnt use a page generator of any kind, hand coded the whole thing from scratch. any idea whats going on? thanks so much!

IHBT. I don't really do much web design but from experience retards complaining about seemingly trivial stuff being broken in decent browsers are doing it terribly wrong, that is, they are butthurt idiots that can't even manage to copy example code correctly.

Dear troll, maybe you're talking about "setting the height of an element as a %" as seen in http://www.positioniseverything.net/round-error.html ? Because it certainly renders correctly for me in Firefox (not to mention Firefox 3 has already fixed the rounding error that page is talking about).
