 * severity:  Critical => Normal


Comment:

 Cookies (and other persistent web data) are isolated by first party, and
 automatically cleared when closing the browser, or getting a new identity.
 Otherwise the functionality is not removed, only the UI. Feel free to
 change `network.cookie.cookieBehavior` - but I recommend you don't or you
 will stand out : `0`=Accept cookies and site data, `1`=Block all third-
 party cookies, `2`=Block all cookies (as of right now)

 DNT is `unspecified` by default by Tor Browser, so all TB users look the
 same in this regard. Again, I recommend you do not change this (also
 behind a pref), otherwise you will really stand out. It is also loosely
 tied into Firefox's ETP.

 The entire about:preferences#privacy Enhanced Tracking Protection (ETP)
 section, including the DNT option, was removed from the UI because .. as
 gk says: https://blog.torproject.org/comment/284777#comment-284777

 > That UI is misleading in a Tor Browser context, though, as it claims the
 browser provides privacy by blocking. We don't believe that's actually the
 case in general and definitely not in Tor Browser's context

 So, long story short: you don't **need** these: change at your own risk
