I have a laptop with a 3840x2160 screen and a second monitor with a 1680x1050 resolution. The standard Firefox DPI is far too small on the builtin screen, but when I scale the layout.css.devPixelsPerPx value in about:config, the second monitor's Firefox UI gets cartoonish-ly large. Is there a way I can get Firefox to look consistent across both monitors? I am running Firefox version 63.0.3 on Ubuntu 18.04 with KDE Plasma. In my experimentation with the settings, it appears that 2.5 works well for my HiDPI screen and 1.0 works well for the external monitor.
