Now here’s one for a dose of retro. How about some Pacman on your Firefox? Yup, that’s right. You read it. Play Pacman on Firefox. with the Pacman add-on.
It plays pretty much like your good old Pacman game. It’s pretty much straight up (complete with the retro sound effects) only you get to play it with four different speed settings – slow, normal, fast and insane. Plus you get a high score list.
