title: Selenium hangs instantiating FirefoxDriver
body: <p>I try to get started with selenium (downloaded the current version today) and copied their example which opens a browser and performs a google search.</p>
  
  <p>However, the program hangs forever in the 1st line <code>WebDriver driver = new FirefoxDriver();</code>.</p>
  
  <p>I have Firefox 13 installed.</p>
