 Sorry for the late review. This patch looks good to me -- nice work! I
 have a couple of minor stylistic suggestions that you may or may not want
 to adopt:
 +// given socketFile or host and port.
 +io.asyncSocketStreams = function (socketFile, host, port) {
 +  let socketTransport;
 +  let sts = Cc["@mozilla.org/network/socket-transport-service;1"]
 +         UNBUFFERED = Ci.nsITransport.OPEN_UNBUFFERED;
 +  // Create an instance of a socket transport.
 +  if (socketFile) {
 +    socketTransport = sts.createUnixDomainTransport(socketFile);
 +  } else {
 +    socketTransport = sts.createTransport(null, 0, host, port, null);
 +  }
 Maybe move `let socketTransport` down to after the comment `// Create an
 instance of a socket transport`? Also, in that file, I had used blank
 lines to separate functions, though that's probably a personal

 Also, a somewhat bigger suggestion that could be part of this patch or
 left for another time. In `torbutton.js`, we will now have
  var m_tb_control_socket_file = null; // Set if using a UNIX domain
  var m_tb_control_port = null;        // Set if not using a socket.
  var m_tb_control_host = null;        // Set if not using a socket.
  var m_tb_control_pass = null;
  var m_tb_control_desc = null;
 I imagine it might be cleaner to collect these into a single data object
 var m_tb_control = { socket_file, host, port, password, descriptor }
 Then we could factor out a single factory function from `torbutton_init()`
 that generates this object. And we could use this object as a single
 argument for functions in `tor-control-port.js` and `tor-circuit-
 display.js` as well.
