This add is promising a lot but it does not delete cookies even the function is activated.

This is a terrific privacy enhancing addon. It works exactly as advertised for me. Thanks for your excellent work and ongoing support.

Ein super Addon um Cookies ganz gezielt und differenziert zu verwalten. Um Klassen besser, als die eingebaute Cookie-Verwaltung des FF. Das Benutzermenü ist hervorragend strukturiert und verständlich. Mit Grips und Liebe zum Detail programmiert. Für mich ist es ein "Brot-und-Butter"-Werkzeug geworden, das auf jeden Fall in meinem Firefox dazugehört. Den Autor kann man auf der Webseite camp-firefox.de auch direkt erreichen.

A great addon to manage cookies in a targeted and differentiated manner. Classes better than the FF's built-in cookie management. The user menu is well structured and understandable. Programmed with brains and attention to detail. For me it has become a "bread and butter" tool that definitely belongs to my Firefox. The author can also be reached directly on the camp-firefox.de website

Works as advertised. Great addon!

The rating is biased with people that don't read documentation, should be way higher and with way more downloads. Work as intended and is a really good feature, I'm certain this will become default someday. Thanks for the hours invested in this Addon!

Thank you for this awesome addon! This should become core for Firefox!

I don't know if I'm doing anything wrong, but I can't get it to work on https://demo.agektmr.com/storage/ for LocalStorage, and I don't know other method to see if LocalStorage is actually working in this addon.

Edit:
I'm sorry, I don't know what I did before, but it actually works!
By the way I suppose it's normal that "SessionStorage" on this site doesn't get instantly deleted on Manual Cleanup regardless of "Protect currently...", I have to close the tab or restart the browser (I'm on v70.0.1(64-bit).
Also can this Manual Cleanup do more than the built-in "manage data" from about:preferences#privacy?
Thank you.

There are a lot of settings and I did my best to be logical when I went through them. Most importantly I assumed that if I mark expressions "Never" they will not be deleted. Not so unfortunately. I keep getting messages at the bottom of FF that so and so cookie has been deleted, even though I marked them NEVER. That is a major nuisance, so I've had to disable it for now.

Does not work. Firefox 70. Cool interface, but automatic cleaning does not work at start or exit of firefox

Working very well; only request atthis point would be some more detailed documentation for some of the specific data types (how to select/clear). Thanks for a really good tool!

I used to think this add-on was more powerful than "Cookie AutoDelete". However, there are bugs, with cookies not being deleted, and this add-on is not maintained (cf. https://github.com/Lusito/forget-me-not/issues/288 ). In contrast, "Cookie AutoDelete" works perfectly fine, and it is maintained!
