Great tool Rated 5 out of 5 stars
Finally a perfect and automatic Cookies Manager.
The extension however, takes about 2.5 Mb.of RAM, is possible decrease this parameter?
You can check this with the extension "about:addons-memory"here: https://addons.mozilla.org/en-US/firefox/addon/about-addons-memory/
Only a one cosmetic suggestion, maybe is better a throbber effect for the icon when the cookies are destroyed.
