MathPlayer Behavior: What to Do?

[BobG]

What's up with getting the following message:

This website wants to run the following add-on: 'MathPlayer Behavior' from 'Design Science Inc. (unverified publisher)'. If you trust the website and the add-on and want to allow it to run, click here...

Is this a new feature? If we don't trust the website and don't want to allow the add-on to run, will the message eventually go away?

Don't install it. I bet it has to do with MathJax. I'll send them a note.
