I was never clear on this extension. Does it just suppress the the cookie prompts, does it only accept essential cookies or does it do the default action and accept everything?
> 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.
At least that is how i implement google analytics for example.
By not showing the button in the first place, nothing happens and no cookies are set (apart from the functional ones which are set regardless).
Other than that it really does not matter that much because if you use a plugin like this you will usually use an add blocker as well which removes the tracking.
