title: How to make Firefox use a proxy server for localhost connections
body: <p>I have a SOCKS proxy forwarding port 9999 on my local machine to a remote development server. I use that proxy connection with Firefox so that I can access the dev server's network, but I also want to be able to forward localhost connections in Firefox to the remote server's <code>localhost</code> to connect to various services running there. I have removed <code>localhost</code> and <code>127.0.0.1</code> from the "No proxy for" setting and it still doesn't work. How do I make it work?</p>
