Noticed the 30th anniversary of Pacman tribute with an interactive game on top. Played with it for a while. Had to get back to work. Needed to restart Firefox (Adobe update, separate story!) Gotten Firefox back up... and the sound of Pacman keeps coming up! There is no window open in Firefox with google.com page on it..... yet, the pacman sound keeps going and going and going.. Drives me crazy. Anyone got a solution? Restarting Firefox did not help. Thanks!
