Font scaling issue on dual monitor setup 3440x1440 and 3840x2160

I am running a dual monitor setup. My primary monitor's resolution is 3440x1440, and my secondary is 3840x2160.


The text on my Firefox toolbars and menus looks very clear on my secondary monitor (3840x2160), it looks as I would expect it to; however, on my primary monitor (3440x1440) it's smaller which makes it pixelated meaning it's much less clear. I've been using Firefox for about an hour and I'm already bugged enough to post here.


Due to the different resolutions I need to keep the layout.css.devPixelsPerPx in about:config to the default -1.0 so the windows scale as per my Windows 11 settings.
