In my setup only three of them are altered from the default values.

privacy.resistFingerprinting privacy.resistFingerprinting.block_mozAddonManager privacy.resistFingerprinting.letterboxing

“privacy.resistFingerprinting” is the one i was talking about specifically, which works for me in the scenarios detailed in my response.

It’s been a while since i setup this install but i know i used the arkenfox scripts as a baseline.

I have no idea how much deviation i have for the default baseline so YMMV greatly.

I only mentioned that setting because it’s one i use to fix my specific problems and it might help as a starting point.
