Review for CookieKeeper by blueduck
Rated 3 out of 5 stars
CookieKeeper has a somewhat confusing user interface. In one window you can select to protect cookies, but another window requires you to exactly type in web sites that are to be protected (or blocked), and does not show the ones already designated as protected. Leaving aside the exact address window, which appears to be useless, the add-on is great.
This review is for a previous version of the add-on (1.8.5.1-signed.1-let-fixed).You are confuse with the cookies protection (which are not deleted by cookiekeeper clean functions), and the website permissions, managed by Firefox itself, which allow or deny a particular website to store cookies.
Anyway, with the version 1.9, you can change the permissions easily as well.
