Thank you very much!

Simple and convenient way of keeping tracking cookies to a minimum without getting in the way of a good browsing experience

This add-on is a must have for security engineers or security conscious people as well as developers (including QA). The capability to allow cookies for specific sites while deleting them for other sites while supporting Firefox's awesome container tab feature pushed the 5th star for me.

I hate having to login to certain sites over and over, especially if I've enabled two-factor authentication on my account and can't be bothered opening Authy on my phone every time, so I like to keep my cookies for as long as possible. However, an overabundance of cookies in your Firefox profile directory is both a privacy and a performance nightmare, and it's often necessary to clear your cookies in order to correct certain browsing issues, which means re-logging into all of your usual haunts.

With Cookie AutoDelete, you can choose which cookies you want to keep, and it will automatically (or manually, if you like) delete all of the other cookies that you haven't specifically protected. It protects cookies by whitelisting URLs whose cookies you want to keep, and you can choose only to protect certain types of cookie from specific sub-domains. You can also specify how often and under what circumstances you wish the add-on to silently clear unprotected cookies in the background. If you like, you can have the add-on notify you every time it does this. The toolbar icon shows the number of cookies the current URL is generating and the icon is also colour-coded to show whether or not cookies are protected on the current URL (blue for "yes", red for "no"). The convenience and usability of Cookie AutoDelete is very high.

There's not much in the way of competition for this add-on, it's simply the best of its kind that I've used. I'm including in that comparison those cookie-management add-ons which are exclusive to other browsers like Chrome.

brutale disparition des addons jugés obsolètes par Mozilla !

Super useful and flexible!

The "clean" button is confusing. There's no indication of what it does since it doesn't seem to affect the current domain. I always use the dropdown to do the cleaning I want.

It was confusing that this isn't like Self-Destructing Cookies in that cleaning cookies and localstorage when you leave a domain isn't enabled by default. But worse, even when that's enabled, it doesn't work properly. I keep having to use the option to manually clean cookies for domains I last visited days before (mainly news sites that give a limited number of articles per month and warn me that I have only one article left). I have an older system with the Self-Destructing Cookies extension and it has no such problems with the exact same sites.

love it !!

just grt extension
