334881 J Query Pop Up

I have a simple popup that is not working completely. goto www.leatherbelts.com. scroll to the bottom. click about solesu. click the last word in the paragraph FAQ. This should pop open a presized window but it only works in IE. It does not work in mozilla browsers for some reason. I need this fixed. should be quick and easy for a javascript pro. the file for the popup code is here [login to view URL]
