 Replying to [comment:2 cypherpunks]:
 > Support of localhost was destroyed by
 [https://gitweb.torproject.org/torbutton.git/commitdiff/71aa3e36b4d95b8b17a06a7cfb9d2f0fe9e813c7
 MiCthulhu] because code wasn't maintained.
 "Support" (a DNS hole) was destroyed when Firefox started to obey Remote
 DNS rule. Tor refuses to resolve "localhost". So, even if you add
 "localhost" to {{{network.proxy.no_proxies_on}}}, you get "Unable to find
 the proxy server" webpage.

 [https://bugzilla.mozilla.org/show_bug.cgi?id=280280 bug]
 Fixed.
 > and then possible to put ''localhost'' back to
 ''network.proxy.no_proxies_on''.
 If you put something there, you get:
 {{{
 Torbutton INFO: aProxy is null
 TypeError: originalProxy is null domain-isolator.js:77:7
 }}}
 Should Tor Browser allow it?

 p.s.
 > I typed in the address bar of the TOR browser ‚Äčhttps://127.0.0.1 and
 it's working.
 Bug. Fixed. In TBB 6.5a2:
 {{{
 [08-21 17:26:30] Torbutton INFO: tor SOCKS: https://127.0.0.1/ via
 127.0.0.1:2f492e7768755f3b659f4dcb9c781b59

 address [scrubbed].
 }}}
 But if you add "127.0.0.1" to {{{network.proxy.no_proxies_on}}},
 firefox.exe starts to connect to your xampp.
