Should be default in Firefox! Rated 5 out of 5 stars

This a simple and much needed feature that should be by default in Firefox with some sensible settings to expire cookies after a week or month or so. The extension description should describe how to use this (go to Addons Manager, select options of this extension).

This review is for a previous version of the add-on (3.1-signed). 

Okay, fixed the description. Thanks!
