Layout tweaked in FF

Hello,

Im having trouble with FF.

http://www.lakejohnson.org/v2/css/friends.css

Everything is fine in IE but FF is will not display correct.

Ive used this same css code on other sites with a similiar layout and it worked fine, I cannot figure out what's going on, any ideas?

Thanks
