How can you setup firefox to disable connections to third party domains (piefed.social)

To easy understand what i am saying, i will give you this example, you visit domain.com but on this page there are other things from external domains other than domain.com that firefox fetches/connects to - cdn.blabla.com; third-party.socialwebsites.com, etc. What i want, is to simply not connect to any other domain except what i typed in url bar. I understand it can break pages but i dont care.
A while ago, setting permission.default.images to 2 somehow worked and stopped loading of external content. Disabling prefetch/preconnect/predict/predictor does nothing.
p.s. i dont want to use extensions, only about config.

uBlock in expert mode provides a similar interface. It's not able too fine tune at the same level though.

I use uBlock Origin + uMatrix together. Didn't know uBlock can do that. Need to look into the expert mode more.

Hey, in case you didn't find or another user is interested, here is the wiki documentation part for the different blocking modes (easy, medium, hard).
