Firefox display problem

My shopping cart page looks fine in IE, but the icons are misaligned and missing an image in Firefox. How do I fix this? I have attached screenshots of what it should look like, and what it looks like in FF. Below is my tpl_shopping_cart_default.php.

I also have a bottom border around my product images (in product detail page) in FF that doesn't show up in IE. CSS already has the following defined:

a img {border: none; } 

TIA!
