I use the Arkenfox user.js repository for my Firefox profile, with a few lines in the user.js file modified to make it easier to use such as keyword.enabled set to true and browser.startup.page = 1 and other stuff, installed UBlock Origin, Decentraleyes, Dark Reader, Cookie AutoDelete, and Multiaccount Containers with certain cookies set to never delete within those containers. I have taken three different browser fingeprint tests from different sources and it does great in all three tests with super solid fingerprinting resistance. It is, in my opinion the most private yet very usable and daily driveable browser.
