title: unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055) ubuntu
body: <p>I had working selenium with my firefox, but today morning when i ran my test i got the same error. I updated selenium-webdriver for current version ( 2.38 ), but i still have that error.</p>
  
  <pre><code>Selenium::WebDriver::Error::WebDriverError:
  unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055)
  # /home/user/.rvm/gems/ruby-2.0.0-p195@taxand/gems/selenium-webdriver-2.38.0/lib/selenium/webdriver/firefox/launcher.rb:79:in `connect_until_stable'
  </code></pre>
  
  <p>also</p>
  
  <p>i checked it in my other project where i have 2.35 version and it also worked yesterday - and there it also doesn't work today ;o</p>
  
  <p>So i suppose that is no selenium issue, but my FF can be broken? But i also tried to run it with custom firefox_path to older firefox versions, and the issue is the same :&lt;</p>
  
  <p>Any ideas?</p>
