title: Set proxy.socks.port selenium
body: <p>I am used to setting http port like this:</p>
  
  <pre><code>profile.set_preference("network.proxy.http_port", "PORTNUMBER")
  </code></pre>
  
  <p>and that works . 
  But now I need to connect with socks proxy and set the port, which it's not working  </p>
  
  <pre><code>profile.set_preference("network.proxy.socks_port", "PORTNUMBER")
  </code></pre>
  
  <p>I couldn't find a reference in the docs and that's why I am asking here.
  Any ideas ? Is there a better way to do it ? </p>
  
  <p>Thanks </p>
