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.
