A bit disappointing Rated 4 out of 5 stars
I installed this because it sounded like a good thing, but what I don't like is once you set a restriction/permission value for a cookie there is no database of these cookies (similar to how noscript, abp and ghostery have something you can go and look at if you change your mind about a site) and you are forced to visit the site again which would result in happening upon the site again, unless it's a site you visit regularly. It's a good idea but it needs some work.
Edit: Okay, that's there (also a bit embarrassing for me since I clearly didn't look hard enough), it does open ff's cookie manager. It doesn't tell me which are edited by cookie monster, better privacy or are my own. But that's probably a problem with ff's cookie manager. Guess I'll try it again and update my review then. I have added two stars, one for pointing out how to find that without pointing out it was my own fault (which I freely admit), and for having that feature there.
Listing of Permissions (Exceptions)
Actually, there is a list of the cookie permissions set for sites, and it is available by selecting View Cookies -> Show Cookie Exceptions in the Cookie Monster menu. Not only can these permissions (exceptions) be viewed, they can also be removed and new ones can be added.
Thanks for trying Cookie Monster.
