Add feature: Exceptions feature in different ways

When configuring my browser settings to clear data on exit, I’d like to set exceptions, particularly for YouTube. This way, I can keep my account signed in and swiftly access my music mix on it.

P.s.: also for “forget me when I close this site”

Actually it would be great to have an option where you add a site and you can unflag all the privacy options you set for all the others websites!!
