I am seeing the FireFox issue, I think the CSS needs to be tweaked a little more. I am investigating the results for the search items now.. Thanks for the bug finding!
I like the bold styling but it's a bit too big and clunky IMO - you've got "Create your FREE wish list" then "Create Your Ultimate Wish List" then "Create the perfect wishlist for ..." all one after another. Instead I'd have this up next to your "WantsThis" banner with maybe one body text repitition above the fold, not 3. It's all a little bit too busy IMO.
Also perhaps indicate on the direct purchase links (images in the top products lists) that they are buy links.
