User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:74.0) Gecko/20100101 Firefox/74.0
Steps to reproduce:
I have tried two 4k monitors of different sizes with firefox and it doesn't scale depending with the DPI and the new zoom option doesn't zoom the UI so instead of editing layout.css.devPixelsPerPx in about:config just add that option to the preferences.
Actual results:
Firefox doesn't scale the UI on high DPI monitors.
Expected results:
Firefox should scale or adapt zoom level on the preferences to use layout.css.devPixelsPerPx

No, this is the wrong solution. This shouldn't be a checkbox or a thing users have to adjust manually, Firefox should just do the right thing and scale using whatever per-screen DPI is configured in the OS. It already does this on Windows and mac and supports per-window DPI (so if you have one window on a hidpi laptop and one on a lodpi external screen, we use the correct (different) DPI for both windows).
If it's not working on Linux, something is wrong in the widget/layout pipeline on that platform.

I'm not using scaling on the desktop, I find the desktop fine as it is, the same cannot be said about Firefox and I require a scaling of 2 to use it.

I've tested the desktop scale and firefox does scale with the desktop setting, sorry about the information was not completely correct, so here what I am asking is an option to manually scale all in the preferences using layout.css.devPixelsPerPx

Going to close this and continue to use layout.css.devPixelsPerPx
