Tab Problem in Firefox and IE6

[ChroniX]

I have had to add tabs to the top of a website I made. I have tried everything I can think of to get them to look right, and they do in Safari and IE7.
But in Firefox and older versions of IE the tabs get a space underneath them, where they should meet the grey line.

Preview the site here. (http://betars.freehostia.com/test/index.html)

Any ideas how to fix it?

It seems to be loading fine. There might have been a problem with the server at the time you logged on, and I don't know what hack to use to get it to work right.
