Doesn't seem to work anymore. Doesn't delete cookies not in the whitelist. They just remain even after restarting firefox, despite manually doing with clean button. Can confirm by visiting Privacy Settings > Manage Data.

This used to be a great extension, but it no longer works. Cookies from sites that are not on my whitelist are not being deleted. They remain after I restart Firefox and even after manually clicking the “clean” button.

Abandoned Extension; no updates in over a year and a half. Very hard to sync across devices if you use Container Tabs. Doesn't seem to be compatible with recent Firefox cookie changes; I found dozens of unexpected cookies which were not autodeleted.

No longer works, save your time. Unfortunately there is no way to 'Automatically delete unwanted cookies from your closed tabs while keeping the ones you want' as there are no controls or drop down menus available. Extension last updated 2 years ago.

What a dumb interface. You need to make it LOUD & CLEAR what each button does. I just erased all the cookies for all of my website logins ever because the stupid drop-down menu of the "Clean" button decided to wipe out everything and not just the cookies for the site I was on. Stupid. Nowhere in any app/ext/software is something that detrimental so easy to do with the click-of-a-button, for good reason. There was no warning at all. Clearing the cookies for the current site should stand alone as it's the most common function for the average user, period. Not an opinion.

It's so quiet here ;) No more annoying "click me" screaming Cookie banners. Love it!
I use it with "I still don't care about cookies", so I don't even have to worry being followed on my cookie crumb trail...

I am very sorry to say your addon sketches up an autodelete operation set up within settings, then the simulation goes further into popping up a notification saying cookies were cleaned, but then I use another method of cookies detection and I find them all there, tens of them and i clear them manually myself. I had to remove your mind manipulation scheme. Thank you for the big show. At least your addon knew to say is active and collecting my data.
