This is now getting very annoying. I am using Safari 5 on my Macbook Pro. Suddenly today morning when i tried stream a video from YouTube, i suddenly saw a message saying "blocked plug-in" and video stopped working. Refreshing dint helped. So i restarted the browser and now it shows me message to update Flash Player.
I simply updated the flash player but still the same message "blocked plug-in". Can anyone help ?
