I am a Tor user. I logged into BitcoinTalk with Tor by choosing 'always stay logged in'. Then, by mistake, before I log out, I did a Tor restart for a new Tor identity. This killed the tab with BitcoinTalk session. Now, I have created another session to log in through Tor. When I'll log out from here, will I be logged out from the other session as well? If not, then how do I kill that session, on which I have lost control?
Try it now in any browser, or activate the privacy mode (do not activate cookies). When you log out of any session, this will cause the automatic exit of all browsers that you were entering.
Or is your question about deleting cookies in one of the browsers (Tor) without logging out?
