Comment:

 This requires two patches, one for Tor Launcher and one for Torbutton:

 https://gitweb.torproject.org/user/brade/tor-
 launcher.git/commit/?h=bug20111-01&id=f221ec51c347a354bd58a6b8bb628f29dee1e284

 https://gitweb.torproject.org/user/brade/torbutton.git/commit/?h=bug20111-01&id=9f6332a4aeb1d3b1a575cebba95903573aab11b4

 Kathy and I propose that we leave the browser defaults as-is. Inside tor-
 browser/browser/app/profile/000-tor-browser.js, we have:
  pref("network.proxy.socks", "127.0.0.1");
  pref("network.proxy.socks_port", 9150);
 That means that a TCP SOCKS port will be used if Tor Launcher is not
 installed, which seems okay since we do not know what path to use for the
 socket.
