Comment:

 Here is a patch for review: https://github.com/acatarineu/tor-
 browser/commit/26345

 I think with the current preferences we should not be blocking anything
 from the Firefox
 Enhanced Tracking Protection/Content Blocking, other than the 3rd party
 cookies (which is the same as esr60).

 With respect to that, Firefox moved the UI for changing cookie blocking
 preference (`network.cookie.cookieBehavior`) to the new content blocking
 section in `about:preferences`. If we hide that (as the patch currently
 does), there is no way that users can change it via UI. I'm not sure if
 that's so bad, since this would only be for advanced users that know what
 they are doing, and still is possible to modify it via `about:config`.

 We currently block all 3rd party cookies (although there is #21905 to
 revise that), and this makes the "shield" icon in the siteIdentity UI
 appear, so that had to be hidden too.

 There are some requests because of this feature going in the background
 from time to time. The ones that I have checked are coming from
 [https://searchfox.org/mozilla-
 esr68/rev/b1a2c428a9125ade87001bb6b9e990c886dcfd31/netwerk/url-
 classifier/UrlClassifierSkipListService.jsm#106
 UrlClassifierSkipListService.jsm]. But I guess we can deal with that in a
 separate ticket together with some other background requests that are
 still happening.
