title: Why am I getting the selenium error 'firefox-bin quit expectedly' and unable to connect to host 127.0.0.1 on port 7055
body: <p>I am trying to run selenium 2.25.0 on a macbook pro with eclipse. I have created a simple class using the documentation example code. The code errors on this line:</p>
  
  <pre><code>WebDriver driver = new FirefoxDriver();
  </code></pre>
  
  <p>with the message:</p>
  
  <p>Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
  dyld: unknown required load command 0x80000022
  dyld: unknown required load command 0x80000022</p>
  
  <p>I have tried downgrading firefox from 15 to 14, 10 and 9, but none of those worked either.</p>
  
  <p>Very grateful for any help anyone can offer! Thanks!</p>
