Remove "New Private Window" option from Tor Browser or make it a separate session
It doesn't do anything that I can tell. If it does, we should have more of an explanation to set user expectation.
For instance, I thought perhaps when I was logged into Twitter in another tab, it might isolate a separate session, but it does not. If I go to twitter.com in a "New Private Window", I am still logged into the same account.
