title: Firefox version supported by selenium webdriver 2.25.0
body: <p>I restarted working on an older rails project today. One problem driving me crazy is that I can't get my javascript test cases to run, although I remember them all passing when I left the project. I am using</p>
  
  <p>selenium-webdriver 2.25.0
  capybara 1.1.2
  cucumber 1.2.1</p>
  
  <p>but firefox doesn't start when I run the tests. All I get is </p>
  
  <blockquote>
    <p>unable to start Firefox cleanly, args: ["-silent"] 
    (Selenium::WebDriver::Error::WebDriverError)</p>
  </blockquote>
  
  <p>I guess this is because of updating firefox and I tried to install several older versions but none of them works. Which version is supported by selenium-webdriver 2.25.0?</p>
