Without the *functional* cookies (which allow the add-on to store its settings) it can not work. You either have to accept them or you can not use the add-on. As per the rules set out by Mozilla we have to show this page and ask for permission for this basic functionality.

Just to be clear: The add-on does not use cookies to track you in any way.

We do not require an account at all. For support, please contact info@keepa.com
