adobe flash player settings

In general, this dialog only get displayed if you've modified Flash Player's privacy settings from their default values.

To change this back, go here:

Set the slider to something reasonable (100K), uncheck Never Ask, and check the Allow Third-Party box. 

The fact of the matter is that for the people that make content that you want to watch to get paid for their work, they rely on advertising dollars.  The advertisers require accountability and tracking information, which if you deny, prevents the content providers from getting paid.  In turn, content providers will sometimes require that those features are enabled before you get access to the content.

Hope that makes sense.
