title: Change proxy settings in Gecko Webbrowser at execution time?
body: <p>I would like to test a list of proxies by loading X page each time with the next proxy in the list.</p>
  
  <p>I'm using a Gecko webbrowser (<strong>GeckoFX</strong>), how I can change the proxy IP:Port at execution time on the webbrowser control to open a webpage using other proxies?</p>
