This is utterly, but just utterly, fantasmagorically brilliant. May not be hard to implement (everythings hard) but someone has done it, and done it brilliantly. Just love it when "150 cookies deleted..." comes up on the message tag!

Gr8 Add-On!! Also Available On Android FF!!! It Seems To Work Just As Described!!! I've Been Using CookieAutoDelete A Year Now...It's Very User Friendly...U Can Just Set It & 4get It, As Well As Enable Some Key Features. Thank You CAD...

There in a class of there own

Refusing cooking outright breaks a lot of sites, but this plugin gets around that

Very useful addon. The integration with Containers is especially useful. You can also backup and restore your settings.

This is a very easy to use, privacy enhancing feature. Once you've setup the whitelist, you don't even notice it doing its thing in the background anymore.
Notifications available for nerds like me who like to know that stuff. A great addon, thank you.

Finally I can open Gmail tab and be sure not to stumble into any mailbox left open by my wife or son previously.

Delayed autodelete is also precious, just set it to a quite long time (i.e. 5 or 10 minutes) and you can still reopen that mailbox tab you have mistakenly closed, without having to retype your credentials.

Thanks so much for this addon!

PS. A BlackList feature would also be appreciated. I often need to delete cookies only for particular sites (i.e. webmail sites, social networks, etc.).
