Firefox scaling on Retina Macbook vs External 1080P display
On my Macbook Air M1, Firefox's UI and default scaling is perfect on my Retina display, but if I move the window to my external Philips 1080P monitor, some - but not all - interface elements are very over-sized, which makes Firefox unuseable on any external monitor I connect. (I have tested this with multiple other monitors)

Just as an amendment to the above, the only interface elements correctly scaled on the external display are the window controls.
