title: Selenium test for Firefox on CloudBees
body: <p>I'm running Selenium on cloudbees. During the run I am getting the following error:</p>
  
  <p><code>Failed to connect to binary FirefoxBinary(/usr/bin/firefox) on port 7055; process output follows:  Error: no display specified Error: no display specified  Build info: version: '2.25.0', revision: '17482', time:  System info: os.name: 'Linux', os.arch: 'i386', os.version: '2.6.34.7-66.fc13.i686.PAE', java.version: '1.7.0_04' Driver info: driver.version: FirefoxDriver</code></p>
  
  <p>Am I missing anything? I suspect that I need to set something for Display because the Error says <code>no display specified</code>. </p>
