I have Firefox RFP enabled, and as far as I know all these values will be the same across RFP users except the size of the browser window (which seems like a poor fingerprinting metric given the fact I can and do resize my browser during usage) - and maybe pixel density? (can't tell if this one is standardized or not).

If there are any other RFP users out there compare to mine and see if you get anything different other than browser window size: https://noscriptfingerprint.com/result/yiRFTom5qPpKPxOl
