Mail message displaying "blocked plug-in"
I used to copy youtube videso and send them to friends via mail... Never had a problem doing so with OSX 10.6.8
NOW alla of a sudden that is not possible and I get a "blocked plug-in" in the body of the message instead of the youtube video...
How do I get to set whatever plug-in I want blocekd or not IN MAIL?
MacBook Pro, OS X Mountain Lion, I regret A LOT having left 10.6.8
