Small and efficient! (with P.S. 18th June 2008) Rated 5 out of 5 stars
Does exactly do what it's supposed to do.
* Finally easy access to the whitelist and the cookie list (there's an own ad-on just for the latter, but it's obsolete now due to this ad-on).
* And the red symbol/button: that's just wonderful. It allows to temporarly access cookie data collector sites (like Google), which are not on the whitelist, just with one click on the red button, and when you're done with that site, click again.
Alexander, thanks for this ad-on!
P.S. Oh, it doesn't work with Firefox 3. That's pity! Will this change soon? Please! Thanks.
