Rated 5 out of 5 stars

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.

This review is for a previous version of the add-on (1.0.2). 

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.
