Stopping Volvo Pop-Ups?

OK - am using Firefox and it takes care of most pop-ups..........except the d_m_ Volvo pop-ups on Answers. am I missing something I can do to kill them.......some days it just keeps coming-back no matter how many time I close it - can hardly read the content. And I sure as well will never buy a Volvo (specially since it's Chinese owned now).
