nice extension Rated 4 out of 5 stars
This review is for a previous version of the add-on (184.108.40.206).
I found the "cookie manager button" very practical. I usually do not open the "show cookies" menu in firefox except for a few critical times when I need to be sure that it does not have a cookie deeply stored.
However "cookie manager button" conflicts" with "cookie button" (at least it does using Mozilla/5.0 (X11; U; Linux i686; en-US; rv:220.127.116.11) Gecko/20061201 Firefox/18.104.22.168 (Ubuntu-feisty). It would be nice if this could be somehow fixed.
