I am also facing the same problem. I was told to install the latest version of Flash Player, so I installed Adobe Flash Player 10.1 by downloading. I You Tube and many other places to play videos in Firefox and Safari. But the videos Vevo rather not getting open. It always throws an error message tells me to install the Flash Player to the latest version. I also removed the option to block pop-ups of the glass. Any suggestions would be greatly appreciated.
