    Bug 13138: ESR31-about:tor shows "Tor is not working"
    
    In Firefox 26 and newer, the BrowserOnAboutPageLoad() function that
    Torbutton previously used to detect about:tor page loads has been removed.
    The new approach is to have about:tor dispatch a custom event (which is
    the same approach Mozilla uses for about:home).
