Why doesn't the Tor Browser (4.5.1), even on the highest security setting disable cookies? They could be used to trace a user, potentially making it possible to build a profile.

Tor browser allows only session cookies. Afaik persistent cookies are treated as session cookies. Press "New Identity" under the green onion menu if you wish to clear cookies without restarting.

  • It's Tor Browser, not Tor. It's a configuration option somewhere, but maybe you'll want an extension like self-destructing cookies, or a cookie saving and reloading extension instead. Commented Nov 25, 2015 at 0:34
  • This answer is incorrect; New Identity is just a shortcut for restarting the browser and wipes all state, not just cookies. Commented Dec 4, 2018 at 6:24
