I have used many cookie "managers" over the years and this is IMO the best of those available for Firefox.
Import/export whitelists and hundreds of cookies deleted at a go. Good stuff here. I would like a bit more larity on how 3rd party are handled. I need to read all the information, I guess :-)
You should give it a try. If I feel the same in 6 months I will donate - as everyone should.
Thanks, Kenny and keep up the good work.

installieren und vergessen; funktioniert ohne weitere Einstellungen schon sehr gut und wenn man doch noch dran drehen will, ist es kinderleicht; es gibt 'ne white-/blacklist, so dass man jederzeit frei entscheiden kann welche cookies man behält und welche nicht;

Einfach und intuitiv zu bedienen, und es tut genau, was es soll.

Very handy. Just gotta watch which cookies it's deleting... if you find yourself having to log into a site when you close the tab & return to that said site, your deletion prefs won't stay saved or anything like that, check the deletion logs to make sure the cookies aren't being deleted by this extension. Easy to white list any important cookies... & if you get lost, they provide instructions for the asking. :) This is cross-browser, so it can be used on other browsers too. :) Just awesome... :D

It was hard for me to give up my old cookie manager, which let me choose whether to accept or delete cookies (with the option of setting them on a per-domain basis). But this works slick as a whistle--whitelisting is easy. I deleted all my cookies to start with (wanting to start fresh), so I didn't run into any problems when I started using this. It hasn't given me any trouble and doesn't slow down my 10-year-old system.

To think that I was relying on CCleaner before this.

Wonderful and very userfriendly. Effective and easy to learn and apply....and allll for free ! i'm loving it !

Invaluable - just quietly sweeps up the crumbs

Funktioniert einfach SUPER.

Perfekt! Cookie AutoDelete ist der allerbeste Cookie Killer!
Vorher hatte ich das Add-on Self Destroying Cookies probiert, aber die sammeln Daten und es funktioniert auch nicht richtig.

Thanks for this great add-on!

it works, simply and reliably

This is my favourite cookie manager; however the one feature I desperately desire is that my settings be sync'ed across Firefox installs.

Since my old pal Prefbar didn't clear the Quantum hurdle, and I used it a lot for cookies, I was forced to find something else. So glad I found this very handy extension. Now with this I leave Firefox cookies ON but a site's cookies are cleared as soon as I close the site's tab. Meanwhile it's very easy to Whitelist a site, so not much repeat logging in. EXCELLENT!

The extension is really good and well designed, but I'll have to subtract one star for the lack of Sync synergy - in this day and age it's unacceptable imho that one should have to go back and forth between different browser instances in order to manually copy over the various extension settings.

Also, on Linux, when clicking on "Export Settings", instead of a file download prompt one gets the JSON file opened within the browser. If it's not something to do with Firefox's limitations on that platform, It should probably get fixed.
