Why does Firefox interupt Farmville2 game (while I am Playing) for a "You are a winner" page and closes Zynga so I cannot play?
All time for the past week when I am playing "Farmville 2" on Zynga, Firefox interupts my game and says "Congratulations you are our prizewinner today." Whatever that is completely closes Farmville 2 and I have to reload it, but it happens again and again and again.
