150% devicePixelRatio: 1 layout.css.devPixelsPerPx: -1 No 2160x1440 Yes Don't know what you mean by chrome but I have dark reader installed

Seems to be 1440 x 807 without letterboxing

Alright so, turning letterboxing on and off with RFP disabled just changes it to 807 and 801. I'll attach a screenshot of the screen info.

Alright so I resized FF to 500x500, moved it to the center and restarted FF. Turns out it opened in 1400x800.

Yeah if I leave the 1400x800 window open and flip RFP off it stays the same. But if I do the 500x500 steps and restart FF with RFP off, it...

Alright so on the control I get 1400x800 and on the test I also get 1400x800. By the way, I'm not using an external monitor, only my laptop screen.
