I do not understand why Sandboxed Tor Browser is now deprecated when it should be the new thing in security features. It works well and stopped already some 0days in the past and today I see that not only is officially "WARNING: Active development is on indefinite hiatus" (https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/Sandbox/Linux), the last commit is from 3 months ago, but still it works well. And today I see that for the Firefox 60 ESR this support will be removed (https://gitweb.torproject.org/builders/tor-browser-build.git/commit/?id=dc355882e235178d0a1889a7d96c5721faad2716).

Is there a hidden agenda to allow LEA/governments to exploit Tor Browser users easily? Because I don't think maintaining the sandboxed version is that much work and it is a great protection for many users.

So please, make Sandboxed Tor Browser an official thing.
