title: Webdriver 2.20 and Firefox 11 (Unable to bind to locking port 7054)
body: <p>I have been using WebDriver with Firefox 3.6 and it works fine. I want to upgrade my Firefox and run my test cases. But for some reason I get the error below when I try to create an instance of <code>FirefoxDriver</code>. </p>
  
  <p>This is how I do it. I don't use hub.</p>
  
  <pre><code>driver= new FirefoxDriver();
  </code></pre>
  
  <p>I even tried using profile.</p>
