brave's default settings are almost certainly exactly what a privacy-oriented person would choose. it does not mine crypto, and it only pays you in crypto to view notification ads if you opt-in. i even gave the ads a shot but decided it wasn't worth the $2 a month or whatever, so now i just have a maintained, de-googled chrome, which is basically a description of the optimal browser in 2021. does firefox ask you if you want to install pocket yet?
If you have to go over the settings... A safe, privacy respecting browser wouldn't resort to any shady tactics in the first place.
