RFP or FPP or both?

Questions
1

I am trying to adjust some configuration fia about:config in separate profile (I am new to this, so I am learning).

What do you think: RFP or FPP? Or maybe enable both?

Mind explaining what is RFP or FPP?
Apparently it’s about
ResistFingerprinting (RFP) and FingerprintingProtection (FPP)

You cannot use both at the same time. If you enable RFP, it takes precedence over FPP.
