title: Firebug disabled in WebDriver after adding to profile
body: <p>I can't seem to figure out why my Firebug extension shows that its disabled when I try to click on it within the Firefox WebDriver.</p>
  
  <p>Here's what my code looks like, I got some of the code from this <a href="https://stackoverflow.com/a/4980226/1393002">SO answer</a>:</p>
  
  <pre><code>private final String firefoxExtPath = "/Users/[NAME]/Library/Application Support/Firefox/Profiles/4izeq9he.default/extensions/";
  private final String firebugPath = firefoxExtPath + "firebug@software.joehewitt.com.xpi";
  private final String firepathPath = firefoxExtPath + "FireXPath@pierre.tholence.com.xpi";
  
  private WebDriver dummy;
  private WebDriver driver;
  ...
  
  @BeforeClass
  public void addFirefoxExt() {
      // Add extensions to FirefoxDriver
      FirefoxProfile profile = new FirefoxProfile();
      try {
          profile.addExtension(new File(firebugPath));
          profile.addExtension(new File(firepathPath));
  
          profile.setPreference("extensions.firebug.currentVersion", "1.11.1");
          profile.setPreference("extensions.firebug.onByDefault", true);
          profile.setPreference("extensions.firebug.defaultPanelName", "net");
          profile.setPreference("extensions.firebug.net.enableSites", true);
      } catch (IOException e) {
          e.printStackTrace();
      }
  
      dummy = new FirefoxDriver(profile);
      driver = new FirefoxDriver(profile);
  }
  
  @BeforeClass
  public void setup() {
      dummy.get(BASE_URL);
      dummy.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
      ...
  }
  </code></pre>
