 Can you explain how this fix is a security hole?

 Sorry, pasted the server side option. But it is still blocked by the Tor
 client by default.

 Fair enough, I guess if people want to extend Tor Browser to support other
 SOCKS proxies, I would not refuse patches that made that more secure or
 functional. But it is not a development priority at this point for us to
 do this.

 It also sounds like you are now asking for an additional patch that
 completely blocks 127.0.0.1 from the browser independent of upgrades?
 Should we also extend that patch to block all RFC1918 addresses from the
 browser, too? This definitely sounds like a separate ticket.

 There are banned ports that are hardcoded in Firefox, like 25. Should we
 use one of those instead?
