Extensions can do that. Not everything needs to be in the core browser, does it?
I think those features should be build by browser vendor. Why? Because pretty much all the existing extensions claiming to "protect privacy" are doing a poor job at it. They all rely on an internal database of "bad guys" as if it's technically possible to even build such a database.
For example, Cloudflare already control a large amount of website through their CDN. They are sending cookies regardless of the do not track headers. I haven't seen 1 of those extensions blocking website using Cloudflare. The do not track header is also a funny joke that even the W3C doesn't respect (https://pbs.twimg.com/media/DWtqPzFUQAExO2h.jpg)
Not all do. uMatrix comes with a whitelist-based approach, so all 3rd party requests (modulo images and CSS if you so choose) are blocked and need to be whitelisted to unbreak sites.
Thank you for proposing uMatrix it just pass the cookie test none of the above succeed, I might have found my new internet condom.

Optionally, unrelated to security you can try "Dark Reader" extension, which makes all sites darker ^_^ Especially useful with darker themes.
