    Orfox: hook up default panic trigger to "quit and clear"
    
    Signed-off-by: Amogh Pradeep <amoghbl1 at gmail.com>
    
    Also:
    Bug 28507: Implement fallback to delete private data in the browser startup
    
    When the TBA is forcefully closed, its private data is not deleted,
    even if the history.clear_on_exit is set.
    
    As fallback, this patch calls the Sanitize:ClearData event in the
    browser startup to clean the private data if needed.
