Rated 5 out of 5 stars

For my own usage this plugin is a "must have" : it's the only one offering a white list for deleting all unwanted or unknown cookies in a snap, and managing the white list is very simple, right on the main dialog window. I don't use other fonctionalities like bloking domains (which seems to have a glitch from reading other comments - I use spybot S&D to set a black list within FF configurations). Thus for that sole functionality I give this plugin 5 stars.
