Comment:

 Kathy and I looked at this and soon realized that we cannot simply modify
 torrc-defaults (SocksPort) and the browser default preferences
 (network.proxy.socks) to use a socket path. This approach will not work
 because we need to insert a full path, and we do not know what the path is
 until the browser is starting up (it won't work to use a relative path, at
 least not on OSX where the TorBrowser-Data directory may be located in one
 of two different locations). Possibly solutions:
 * Modify Tor Launcher to Do The Right Thing and configure tor and the
 browser correctly. This is how we handled the ControlPort.
 * Modify the browser and tor (possibly with help from Tor Launcher) so we
 can use a placeholder within network.proxy.socks and SocksPort, e.g.,
   network.proxy.socks="file:///--PROFILEDIR--/../../Tor/socks.socket"

 Comments? Do you have a better idea? Kathy and I favor the first approach.
