What is wrong with Firefox and cramster.com?

This is what I see when I use Firefox 3.5.5 and go to cramster.com:

Something is definitely wrong because it works with Firefox on my 2 other computers. Sadly it works in IE on this computer so there is something specific about my Firefox config. I tried disabling all my addons and themes, but no luck. Then I tried using firefox’s safe mode and deleting all cookies associated with cramster and still nothing. I noticed there are a buttload of errors in the css but I can’t figure out why this is only affecting my one computer when using Firefox.

Any ideas?
Thanks
