Recently, every time I hit a new page in stackexchange, whether it be the list of questions in a given forum, or a specific question, I am getting a pop-up like this:
Accept all cookies
I am able to click "accept" and it will go away, but it comes back as soon as I reload the page or view a new topic. UMatrix shows it's a script from cdn.cookielaw.org and that it's trying to set a 3rd-party cookie.
My guess is that since I'm blocking 3rd-party cookies and scripts, it just keeps trying.
Given how bad we know 3rd-party cookies are, and how they are used to violate privacy, track people across sites, etc., why on Earth would Stack Exchange do this?
