-Informative preferences
------------------------
-
-The following preferences are set when the remote agent starts the
-HTTPD frontend:
-
-### `remote.httpd.scheme`
-
-Scheme the server is listening on, e.g. `httpd`.
-
-### `remote.httpd.host`
-
-Hostname the server is bound to.
-
-### `remote.httpd.port`
-
-The port bound by the server.  When starting Firefox with
-`--remote-debugger` you can ask the remote agent to listen on port
-0 to have the system atomically allocate a free port.  You can then
-later check this preference to find out on what port it is listening:
-
-	./firefox --remote-debugger :0
