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!

Speaking of which, now that all the browsers support downloadable fonts, maybe it's time to start using them.

And by all the browsers I mean:
* Firefox 3.1 (not released yet)
* The next Chrome (not released yet)
* Opera 10 (still in preview)
* Safari (I think the current version already supports it, feels bad man)
* IE (since version 4 or so, but you have to convert your font and put an extra declaration for IE as usual)

Thanks Acid3! Not that it's really the final solution since font metrics are fucked anyway, you can count on length changing from browser to browser, OS to OS, and antialiasing settings to antialiasing settings. So much for "pixel-perfect layout". In b4 "fixed layout is evil", enjoy your text as images or Flash.

By the way TrueType/OpenType fonts can have hinting microcode embeeded. I wonder if it's Turing-complete.
