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 have a similar problem here. One of the emails I get regularly uses Flash to let me preview the new music added to the site. This worked like a charm all the way through Lion but now I get that same Blocked Plug-in message every place the player should be showing up. Flash works just fine in Safari and everywhere else. Fortunately the emails contain a link to the site so I can still preview the new music but it is a bit of a hassle.

I had trouble with the Flash plugin, after a total reinstale still getting blocked message so I uninstalled Flash


Deleted all references to Flash or Shockwave in Macintosh HD > Library > Internet Plugins > Disabled Plugins


Reinstalled

Restarted Safari and now working


I think the issue is with the Adobe installer program not clearing out references to old versions.

I had the same issue. If you have a blocked plugin, you will have a disabled plugin folder somewhere. It may not be a Safari plugin, but rather Mail.app.


Look in the following foolders:


/Library/Mail/

/User/<your user name>/Library/Mail


Mountain Lion (ML) appends the folder names with "(Disabled)" - something like "Bundles (Disabled)"


Remember the Library folders are hidden by default. To see it, click Finder -> Go To, hold the Option key and you'll see the "Library" entry. Click it to go there.


Move any plugins you find there to a location you will remember making not of where they go. Restart and open Mail. If it works you can move some plug-ins back one at a time to figure out which was the culprit.

May be I wasn't clear in my question, since some answered about Safari.

The only problem I have with Safari 6 is that it is VERY slow in loading pages and that it doesn't have RSS reader incorporated as Safari 5.1.7.

My problems are with MAIL: it is in mail that I either see small blue boxes or messages with "blocked plug-in".

I could not find anything in the Mail folder either. Bundles folder is empty.

It's the same plugin.


There are several places it's been installed over the years, and therefore, where its remnants may be hiding. It may be in ~/Library/Application Support/Adobe/. It may be in ~/Library/Internet Plugins/. There may or may not be a Disabled Plugins folder. Point is that this conflict is highly likely to be the cause of your issue.


Good luck!

Same problem here. Flash works fine in browsers, I get "Blocked Plug-in" when viewing an email with an embedded video. Used to work fine before Mountain Lion. I re-installed the latest flash player (11.3.300.271)


Only file in Library\Internet Plug-in\Disabled Plug-in is Windows Media Plugin


Sure would be nice to see videos in my emaul again.
