While it's true that this extension sometimes accepts all cookies, that isn't the case most of the time. From the extension's website:
> In most cases, it just blocks or hides cookie related pop-ups. When it's needed for the website to work properly, it will automatically accept the cookie policy for you (sometimes it will accept all and sometimes only necessary cookie categories, depending on what's easier to do). It doesn't delete cookies.
It would be helpful to have a "what did you choose on this site" view though if that doesn't exist yet.
