Nice and simple BUT how about a cookie BLACKLIST!
Now that CS Lite seems to be dead, that would be a killer feature to block those advertising cookies without disabling other sites.
Blocking should be possible
Since CWWB is just a friendly (and very whitelist-oriented) UI for Firefox's built-in cookie features, you should be able to go to "Options -> Privacy -> Exceptions" and add sites you want to block there.
