i hoped there are some config values that i am unaware of to do the changes i want.

open source = some parts of the code can be open at best, it isnt what it sound. license matters. this word is just a trick.

yet, i wouldnt count on someone auditing code, there was lots of big projects with trully open code that had bad code injected for decades and noone noticed.

as much as i know, those extensions call back on developer server for updates/new filters etc. so i skip.

what most people do is wrong in most cases. elaboration goes nowhere and in general just derails the topic more.

an extension has access to eveything you visit. it tracks you and sells/shares your data. not to mention potential bad code injection.

waste of time. cat and mouse game.

it was an example, this relates to any domain you visit.
