Just saw that the problem only exists when I choose 'open in new tab'.
Same for me. When I open in new tab, Firefox simply opens the original window in the new tab.
If I do the same in IE (which I don't habitually use), it opens the original window in a new tab plus the vendor's page in a new window.
Bummer really because I typically open such links in a new tab by clicking on them with the middle mouse button – it's quite automatic now.
