Being not happy with the privacy-unfriendly status-quo where I "need to" share data just because I want to view online-content (legitimate consent, ...) I am wondering whether there is a browser extension that aids identifying such websites and spams me with warnings, which could help me avoid these sites in the future even better. I tend to simply decline all cookies I can, but I would prefer an even more drastic solution and not give those sites a view anymore, at all.
Would there even be an extension that could do this on mouse-hover over a URL/link? I guess I need not say the addon should be for Firefox or similarly privacy-friendly browsers; don't answer for Edge/Chrome-only addons ;)
(And what add-ons could also be interesting for a privacy-concerned person?)
