Without seeing your page, I would guess it may have something to do with the CSS differences between IE and FF. Those two browsers do not implement CSS the same way.
It also depends if you are running in Quirks Mode or not (do you have a DOCTYPE?) I've always dug myself out of these types of problems using Firebug in FF to inspect the offending elements to examine the styles applied to it.

I'm using the dimensions plugin. I'm using UL, LI to generate a scrolling grid. #datatableHead ul has my column headers #datatable is a div that's scrollable first I set widths for the head and scroller: $('#datatableHead ul, #datatable').css({width: $(window).width()-20}); then I set my grid rows' width based on the scroller's width - since its all based on viewport size. $('#datatable ul').css({width: $('#datatable').width()}); looks perfect in IE - but in FF the width of the #datatable ul is about 20 px bigger than in IE. now, please don't say: "why use dimensions you should use CSS widths - trust me I tried all of that, it's not working. If only i could figure out why FF renders widths differently? I thought the whole point of dimensions plugin is to make that no longer matter. Thanks! (now I shall look over the list and see if I can help someone else :P )
