This extension has been acquired by Avast (which itself has been acquired by Gen Digital Inc., a large tech conglomerate) and I simply don't trust Avast with my data.

More and more websites are not usable with this addon, you can't click on anything because it hides the cookies popup and nothing else, so this is just a pain now...

It still accepts cookies, including cross-site cookies :(
