Mail message displaying "blocked plug-in"

I am wondering if the problem may lie on the sending end. Perhaps they are embedding an out of date player?

OK, I emailed the site that sends me the email with a flash player embedded and got the following reply:

"It's very possible you're right, that we're using an older version of Flash, so that older browsers and open source types could listen to our music. Unfortunately, I don't think that javascript can be run in an email to auto-detect the right plugin to use.

I'll be looking into this in a few months, when I upgrade to Mountain Lion.

For now, I'm afraid you'll need to click on the links to play the music, like those sad people running windows have always had to do. 😀

Anyway, it will be interesting to see what happens. You might try emailing whoever sends you the the email with the blocked plugin and see if you get a response. I may be completely off base here but it seems like the only remaining alternative as to the cause of the problem.

I'm having the same issue as Sergio. If anyone out there has an answer, I'd love to here it.

My issue is as follows. When copying content from my browser or a web page that contains a flash video and pasting it into Mail, in place of the video there's a message saying "Blocked Plug-in". This wasn't an issue with Snow Leopard and I have the most recent version of Adobe Flash installed.

Same issue, updated plugin and I get "Blocked Plug-in" in the Mail Application but it works when viewing in Safari.

I have tried all of the sugested solutions above and non of them work. I am still recieving a "Blocked Plug-in" error in my Mail message. Do actual Apple employees offer solutions on this forum? My problem email is just a iFrame with a embed pdf and yes I have delted all files Adobe Acrobat and done clean installs to no avail.

I have the blocked plugin error in Mac mail and also in Aperture. It seems to happen with my own images, whether they be jpg or gif.

Here is how it started:

Java v 7 did not work for certain web sites, so I found some helpful site that gave information and commands on how to uninstall Java v7 and go back to Java v6. This solved the problem with the web sites that used Java programming, but ever since then I have been getting the blocked plugin problem.

Mac OS 10.8

Anything?

I was having this problem too. Then I remembered to clean caches. I downloaded Mountain Lion Cache Cleaner, repaired permissions, rebuild prebindings, etc. (see "Maintenance" for more options) and made a deep cache cleaning (also selected the three "clean" options under "Cache Cleaning"). And it seems to have worked. No more "Blocked Plug-in" in the Mail application 🙂

Hope it helps.

Thank you! That did the trick. No more blocked plugin on mail or aperture. I did not even have to go to the deep cleaning.

hi together

you don't need to download any third party software just use the mac os x integrated programm called "disk utility" and then klick on the klick on the main hard drive on which the mac os x is installed the button "Repair disk permissions"

for me this solved the blocked plugin problem in apple mail. (before it blocked any attachments incl. .png pictures)

now all it's fine.

After quite a bit of troubleshooting repairing disk permissions resolved the issue. Seems to be Java.

I've been doing a ton of maintenance since "going to" Mountain Lion - too much, I think.

"Upgrading" to Snow Leopard would work for me, but I'd have to completely re-install my other 2GHz Intel Core Duo iMac, something I'd hate to do because Apple has dropped Intel Core Duo support, I guess a blessing in disguise if I hadn't accepted all the Snow Leopard Security Upgrades on my iMac. If I were to re-install my iMac, I'd go into true "hack mode", because I've used that iMac as a MacPorts development platform for years, and I'd NEVER NEVER NEVER get it back into the state it is currently in. FAIL.

Also, since my PowerMac Dual G5 has been unsupported for so long (what ever happened to the combined PPC and Intel binaries? - I digress), I couldn't even upgrade that FINE BOX to Snow Leopard. FAIL.

My PowerMac Dual G5 box is on my LAN, fortunately, because it's video card burned out years ago (EXPENSIVE replacement and not many video cards were made for this server's architecture), so I can Screen Share into the Dual G5, use its Mac Mail, and all is glorious in terms of embedded youtube vidoes.

Here's the technical details that I really wanted to share before digressing:

No matter which of my servers that I author and view a "copy and pasted" youtube video in Mac Mail (Mac OS X 10.5.8 Dual 2 GHz PowerPC G5 aka r2d2, Mac OS X 10.6.8 2GHz Intel Core Duo aka c3p0, or Mac OS X 10.8.3 2.8 GHz Intel Core i7 aka laptop), only r2d2 can view the content, and c3p0 and laptop cannot. Yay for the underdog i.e. r2d2.

Forgot to mention - I did all the cache cleaning, disk repair, etc. etc. etc. to no avail. The Mac OS X 10.8.3 2.8 GHz Intel Core i7 laptop COULD NOT cut and paste youtube video from Safari into Mac Mail without blocking the content. Hmmmm... Note to self - consider resurrecting Microsoft Entourage (now refered to as Outlook) to see how well Microsoft Mail from Microsoft Office handles youtube video content. Ewwww - The idea of it; low priority task.
