bad header alignment with firefox

Hi. I use the tpl_header.php page to add two custom headers in two languages.

Everything is fine with IE but the images somehow don't align well in firefox.

You can see the site here: https://www.arcanaluminium.com/catalog

What I did is to put the code exported from image ready, from the table tag just after the body tag until the last table tag of my layout. Both for my english and french pages.

I tried with and without rollovers with the same results.

Any ideas?

Thanks

When I look at your source - there is no headerWrapper and others associated with the tpl_header.php.

You have, it appears placed this all into "centershop" and a TABLE to boot.

This is fully outside the div based default and to the images lining up this is a Table issue as in a div based layout this would not be sliced up but a whole image and not require alignment.
