After having used many others I also tried this one for a couple of weeks, but it didn't do it for me. Especially the UI is confusing, enable/disable state is a gamble, you don't see what you're deleting. I ended up using Cookiebro instead, which is more intuitive, easier to whitelist cookies, easier to partly or temporarily black/whitelist cookies, separates sessions cookies, and most of all: You see the exact cookies that are active listed, and can choose to clear them all in one go, or tag the ones you prefer to stay etc. I'm really surprised to see so few are using Cookiebro and so many have picked this one. Cookiebro really beats this one. Easier on the eyes too.

A necessary security add-on that works well and as advertised. Before using, set up a whitelist or you will lose your cookies.

Summary:
Love it. Easy. Automated. Confusing Blue Color.

Strength:
• Open source. If you are not familiar with "open source", it means this app is more secure. Because its code is publicly available for review and contributions on GitHub at https://github.com/Cookie-AutoDelete/Cookie-AutoDelete
• Attractive MIT License. This means the software code of this add-on app is owned and supported by a friendly not-for-profit community. Instead of a for-profit corporation. And more secure because its full code is publicly available for review.
• Easy to use. Using the button in the browser toolbar.
• Whitelist cookies. Very easy. Two clicks to whitelist a website.
• Frequent add-on updates
• “Automatic Cleaning” allow you to optionally automatically delete cookies from closed tabs after a set delay
• Export or import your whitelist of cookies expressions/rules
• Well documented
• Works with Firefox 52 or more recent
• Available for both Firefox/Tor Browser and Chromium/Chrome

• Internationalization (i18n)
• Many more features

Challenge:
• The color of the toolbar icon for whitelisted websites is blue. Which is confusing at start. Because for most extensions the color green is use for whitelisted websites. But after this initial learning curve, the user interface works fine.
• Can not edit cookies. But this can be done with other extensions which focused on software engineer and testing.

Using:
• Extension 2.2.0
• Firefox 52 (64-bit)
• Tor Browser 52 (64-bit)
• Debian 8 Jessie 64-bit
• GNOME 3.14.1

very good

Easy to setup and works as it says.

This is an indispensable privacy tool

Need confirmation before cleaning. The risk of data loss can not be justified by "security".
I mean confirmation by pressing the "clear" button, after accidentally clicking on it instead of clicking on the arrow selection.

How can I add lastpass cookies to whitelist?

Easy to use. Allows you to protect cookies from sites you want to keep, like login sites. Deletes unprotected cookies shortly after viewing page or next browser opening. In the past I was manually deleting cookies every day. I don't like to be tracked.

Useless when you open consecutive sites on the same tab. You MUST close a tab to be effective. What about deleting cookies when a site is no longer active ?. That´s the trick.

I like it

Works flawlessly. Really useful extension. Thanks.

The extension seems good, but it would be significantly better with a 1-line privacy policy saying 'we will never collect your information or track you.' Will update one day if I notice one gets written :)

Love it! I hate when cookies hang around forever for sites that I have only visited once, and this extension makes that a thing of the past. What I don't understand is, why isn't this functionality built into Firefox itself? Hopefully one day it will be, but for now, thank you SO much Kenny Do for an excellent extension.
