Need help fixing FF issue with this site!

[pacer]

I took over this website (http://www.givemebackmyglory.com) for a friend, so it was not built by me. I noticed a flaw in the home page when viewed in FF...clear down at the bottom, the footer is running over the "buy now" link. It looks fine in IE. Can anyone take a look and see if you give me a hint on how to fix this in FF? I know it is probably something very simple, but I am stumped!

Thanks!
