No, nothing to do with TBB of course.
Plenty of sites use tracking cookies and 'beacons' but you might not expect to come across this sort of thing when using SSL i.e secure sites,
but logging in securely to AOL webmail via a direct link, not AOL home page, i was just asked to approve/reject a cert for 'sb scorecardresearch.com'
The only reason i knew this was happening was because recently i looked closely at all the root certs in my browser store and changed a number of them to 'Warn me before using this certificate'
In this case scorecardresearch were using AddTrust External CA Root
they also use a root for UTN-USERFirst-Hardware
it's probably worth changing their status to 'Warn me before using this certificate'
