Great public service - infuriates the ad-tech gods - on that basis alone I'd srsly donate $$ to support.

Now that firefox isolates third party cookies by default, what does this offer as extra protection?

It does not work, at all. Facebook added all new content related to what I just did today. I am told to give feedback if I have problems, but ... no link anywhere on who to contact. Thus, bad review.

Essential add-on on desktop. Would be great to have this in Firefox for Android as well!

Anything that improves my browsing experience is a worthwhile extension.
