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

I tried a a couple of similar solutions suggested here and one of them solved this "blocked plug-in" problem for me. I used Apple Disk Utility to repair OSX permissions and then installed Onyx v 2.8.7 for Mac OS X Mountain Lion and Mavericks, ran the Cleaning module to clear out most of the cache's, restarted the Mac and Mail worked properly again. For me, the "blocked plug-in" problem (for photos) arose after installing the latest Flash update in early September, 2014. Even the toolbar icon to add attachments had disappeared from Apple Mail. Very perplexing.
