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

_____• https://chrome.google.com/webstore/detail/cookie-autodelete/fhcgjolkccmbidfldomjliifgaodjagh
• 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

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.

I like it

Works flawlessly. Really useful extension. Thanks.

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.

great tool!

100% !!!

Works great and improves privacy!

I wanted an app that deletes cookies and this app deletes cookies

I find it really useful, if you're trying to improve your privacy then you need to give it a try.
