How To Disable / Enable Plugins?

We are creating a web application. In there, we would like to disable some plugins installed in the user's browser when the user visit out site, such as video downloaders. Is there

Solution 1:

No I don't think there's really any way around this. Basically you would be controlling their browser (an application on their computer). This is a violation of security and privacy to control someone else's computer in this way.

You can have your site attempt to shut down if it detects such actions, but the technical burden is on your shoulders.

Solution 2:

No, there's no way to do that. But you can make your videos harder to download, for example use temporary video urls, or rewriting your urls.
