 do you want to backport the Mac hardcode in 3?

 Seems reasonable. We are back then to platform discrimination where we had
 possible user discrimination per platform before, so I think that's a win.
 I backported the fix to
 https://bugzilla.mozilla.org/show_bug.cgi?id=1403412 as well (assuming
 that was actually meant :) ).

 Both is available on `tor-browser-52.5.2esr-8.0-1` (commits
 9080c51a22a03aaf8e49d5552253ed716414c760 and
 deaabb54809b2de56b2b5ce98a0f629c1455fcf5) and the plan is to have it in
 the next alpha.
