 * ApplicationAccessible is for the whole application of Mozilla.
 * Only one instance of ApplicationAccessible exists for one Mozilla instance.
 * And this one should be created when Mozilla Startup (if accessibility
 * feature has been enabled) and destroyed when Mozilla Shutdown.
 * All the accessibility objects for toplevel windows are direct children of
 * the ApplicationAccessible instance.
