title: Where do I see what firefoxdriver selenium starts while testing?
body: <p>I have installed firebug for FF. But when i start firefox it always starts some default ff version, i dont' know where selenium finds it.</p>
  
  <p>I already googled alot, tried to use different firefoxbinary:</p>
  
  <pre><code>System.setProperty("webdriver.firefox.bin", "C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe");
  
    final File firefoxPath = new File(System.getProperty("webdriver.firefox.bin")) ;
    FirefoxBinary firefoxBinary=  new FirefoxBinary(firefoxPath);
    firefox = new FirefoxDriver(firefoxBinary,null);
  </code></pre>
  
  <p>I tried to use different ff profile:</p>
  
  <pre><code>FirefoxProfile firefoxProfile = new FirefoxProfile();
     firefoxProfile.addExtension(file);
     firefoxProfile.setPreference("extensions.firebug.currentVersion", "1.9.1");
  </code></pre>
  
  <p>Alas, it does not work!
  1. I don't know where to change/find webdriver.firefox.bin
  2. I have tried changing path as environment variable,still no progress
  maybe I m doing something wrong?</p>
