any time i sign in on the fh PAGE and not the GAME, something usually pops up in a new tab when i click on the 'username' tab thingy. once it opened several tabs all asking me to download something, i couldn't close it out, and had to use incognito for a day before learning i could just right click and do 'close' and i was saved. Whew!
usually for me...i X it out too fast before i can see xD but it's often asking me to download something.
