Rated 1 out of 5 stars

This feature is already in the "page infos" dialog box. You just need to click on "show cookies". This addon is useless as far as I know.

This review is for a previous version of the add-on (1.9). 

View cookies show all cookies that are used on the current page. The existing functionality shows all cookies that matches the domain name, which is very unreliable.
