Thanks for the suggestion and sorry for the huge delay (travel, holidays, etc.).

First of all, at Tails we want our browser to remain as consistent as possible with the behavior of Tor Browser. This is both to ensure that it's not too easy to distinguish Tails users from Tor Browser users but also to grant user with a consistent behavior between both products (assuming that Tails users might also be users of Tor Browser on their regular operating system).

So I don't think that we'd want this extension in Tais unless it's also in Tor Browser. That's why I'm rejecting this ticket.

But also, Tor Browser already has embeded cookie protections. For example, all cookies are deleted when restarting Tor Browser or when using the New Identity feature. I think that this behavior is simpler to grasp by users than manipulating cookies one by one and it already provides an efficient a way of cleaning cookies.
