You may find it troubling that when you follow a link in Tab 1 (Site A) which is targeted to open Site B in a new window or tab, Site B can change the page in Tab 1 from Site A to Site C or whatever. This script adds some rel attribute values to such targeted links to limit the potential for that. It does not attempt to clean up uses of window.open(), however.

Side effect: Site B cannot tell the source of the referral was Site A.
