We have a site running with :CS-Cart: version 3.0.6 PROFESSIONAL
When we display multiple product pages, the Navigation displayed such as "Prev", "Next" and page numbers at the foot of the page don't work with Firefox Browser.
It seems, this page is not marked up properly. Looks like some tags are not closed, but browser closes them by itself. It should be investigated directly on your server
I reproduced it on the clean 3.0.6 installation. Looks like default feature when ajax pagination is used. But the URLs in the pagination bar are correct, so it will not affect your page rank
I tested it in Firefox (where the bug was repsoduced) and in Chrome (where it worked and is working). The fact is that JS works not completely in the same way in these two browsers.
