Warning, no longer works. This project is dead!

A good successor is "Auto-Clear Site Data" by byuserforuser

addons.mozilla.org/en-US/firefox/addon/auto-clear-site-data/

Mais um herói para meu esquadrão!!

This is one of my favorite MUST HAVE extensions... I use it together with FireFox Containers - it's fully compatible.

So it remembers my preferences per container... Random cookies don't stand a chance. The ones I want remembered stay remembered. Just make sure you set it up right. Read their warning about new versions of FireFox and set it accordingly.

Does not work......... No blacklist. No setting to delete everything by default unless whitelisted. wtf is this garbage?

When using machines, and or Win OS that are not the very latest Ex: Windows 10 or below (This may incl. Win 11- Which I don't use) and or if the internet cache is insufficient to workload, esp during long sessions, many sites, (ie: social media, streams etc) can become sluggish, or misbehave in various ways depending on the factors mentioned above. CAD has been VERY helpful to Me, when cleaning the cache, fixes certain cookie accumulation that can hinder optimum functionality.
This extension is excellent when: Configured & compatible with the host device, OS vers, browser settings, running apps/ext. and when used properly, for that which it is specifically designed.
NOTE: It is IMPERATIVE to learn and understand ALL the settings, options and to utilize them correctly. Customize them as per your personal needs. Failure to do this could result in a less then ideal or a negative experience of this fine, useful extension.

It seems to me it no longer works.

Unfortunately no longer works. Says it deleted cookies but the cookies are still there, very deceiving. GitHub Issues ignored, project dead.

What a shame, this is a much needed extension.

This addon is no longer auto deleting cookies that aren't whitelisted. And it seems a number of cookie managers are now suffering the same issue, WTF Mozilla can't add this as a standard features to FF is beyond me.

Needs a blacklist mode.

One of the essential plugins for anonymity. This allows you to control cookies. Firefox have some protection built in but this gives you much more control with whitelists etc just 2 clicks away if you need it which makes it a must to those that want some level of anonymity while surfing the net.

Really useful extension for keeping cookies under control without having to think about it. It automatically deletes cookies from closed tabs while keeping the ones you trust. I like that it supports containers and gives you options to keep cookies temporarily or permanently. It helps keep browsing clean and private, and it’s easy to manage with clear settings. Perfect for anyone who wants better privacy and less tracking without constantly clearing cookies manually.

Recently I've found that all cookies I have are really from the URL (websites) I visit, not with weird names like 000adv.net as before. So, I conclude that this app works well!

This was probably a good extension as of the last update (3 years ago). Now it's abandoned, unmantained, obsolete and maybe even dangerous.

The list of domains has a terrible layout with misplaced scrollbars, very difficult to navigate.

It also requires the following two flags:
* privacy.userContext.enabled
* privacy.userContext.ui.enabled
that I cannot remove in order to disable the useless "container tabs" feature.

Autocleaning stopped working correctly, cookies are not deleted
