Zan Cart version: 1.3.8

Hi,

I have installed the column_layout_grid_for_product_listing mod to make products show in grid layouts. Everything looks nice in IE. But when I open the page in Firefox, things all get messed up!! The borders and header images for the sideboxes are gone! And the products are listed in one column only!

I am not familiar with the browser compatibility issues. Could someone please point me to some directions?

Many thanks in advance!
