 > > I presume you refer to #24351.  As its reporter, I should emphasize
 that on one point you are correct:  I do not suggest that Tor or Tor
 Browser should “block all of Cloudflare”.  Rather, on the application
 level, Tor Browser should provide to users an informed choice—with sane
 defaults, appropriate to the level of the Security Slider.

 (with option to override); at Low Security, I would expect that it be
 permitted by default; in the middle, I am still on the fence.  Moreover,
 at all security levels, ''the lock icon must stop lying to users''.  The
 mixed-content warning on the lock icon provides a good precedent for how
 to proceed here, plus an existing UI graphic for consistency.

 and pervasive.  Do ''you'' know how much of your own `https` web traffic

 reasonable means of measuring this?  Most of all, do you have any means of
 avoiding Cloudflare—short of avoiding the Web altogether?

 Read the title of this ticket. Sure you can't tie Cloudflare-thing to the
 security slider but you can tie "corporate MITM" to the security slider.
