After using Firefox for years, the past month it stops working after a few minutes while playing Farmville on Facebook--this does not happen anywhere else, I've updated, refreshed and reloaded Firefox, Windows 10, Java and Adobe Flash--I've enabled/disabled everything suggested in trouble shoot articles. Don't know what else to do. I've added Opera just to play Farmville but it's very slow (same with Chrome). When I tried Explorer, it also stopped working just like Firefox
