title: Setting default setting to 'no proxy' in Selenium Firefox
body: <p>Whenever I open Firefox using Selenium in python using the command</p>
  
  <pre><code>browser = webdriver.Firefox()
  </code></pre>
  
  <p>The default proxy configuration is set to "use system proxy setting". I have not configured any proxy in the system. Still whenever the browser opens, it says "The proxy server is refusing connection".</p>
  
  <p>How do I open the browser so that the default proxy setting is set to "no proxy" ?</p>
  
  <p>Please help. Thanks in advance.</p>
