 Is it possible for a website to see what other websites the user has open
 in other tabs. I'm wondering from the point of view that suppose someone
 typically opens the same 2-3 websites when they first start using tor,
 (e.g. news sites) and then proceeds from there. If they had done this
 previously without using tor, could this in someway be used to fingerprint
 them, or reduce their anonymity?
