This deserves 4.5 stars, because it really "does what it says on the tin" to use a British expression.

That said, there are two areas that could be improved:
• Import/Export. The docs make it seem easy, but after you do export you find that each entry has a unique ID. How an import handles a collision of example.com whitelist with an existing entry of example.com greylist is "left as an exercise for the reader" as you can find in a textbook after a puzzling new idea is presented.
• Better granularity with subdomains, etc.

The dev does work on this project, so these overly wordy concerns may well be resolved - perhaps soon.

edit: fixed itself...

some sites lose cookies dispite added in whitelist - annoying... (example: https://geizhals.de/)
No Problems if disabling this addon!

I am not fully up to speed on the fine detail of this add-on, but the little pop-ups seem to indicate it going about it's job in an industrious manner ...... which is good, of course!

GUI of this app has a potential to improve. I mean, current state can't be considered as satisfactory. I even gave 1 star to this extension at first :) It easy to mess with it's configuration and be forced to login again to whitelisted sites.
But eventually i stayed with this extension, cause it's the only one i found to be functional on mobile devices. So it's OK, compared to others.

Works but what I would like some option to automatically add all cookies to the whitelist since i don't want to go to all sites and whitelist them.

Please add a blacklist feature where it just deletes chosen sites

I like this cookie-Manager very much. especially the option to add a site instantly to the white list. Great option.
But there a few things i have problems:
1. it lacks an option to integrate all EXISTING cookies to the white list (if i change from another cookie manager very important)
2. the clean up button should not start imidiately. I deleted all my cookies this way.
3. i cannot see all the white-listed cookes
4. where is the option for export/import of white and greylist
But otherwise very useful addon.

I've being using this for a couple of years, despite all the mislead info on the reviews, if you want straight forward cookie removal this 1 is fine, but, I have to admit it took me sometime to finally get used to domain cookie removal, but, not a more fine granular cookie removal without headaches ...
Anyway, thank you Kenny for this add-on, keep up with the good work, Lampadinha

Must have for a safer and secure surf on web. I will give five star if it provide a easy way to just save login-required cookie and clean others automatively
