Unironically, Ecosia has been working on a browser that’s currently in beta with a built in adblocker. Works really well!

my bad, I always assume not just because we’re on the topic of privacy but because of how Ecosia advertises itself as a privacy friendly alternative on their front page when it isn’t that at all that, much like the difference between apple.com/privacy and apple.com/legal/privacy

Your search query, IP address and iirc fingerprint gets shown to Bing everytime you make a search, so it’s not private at all
