With normal mice, when you scroll you typically scoll in steps which you feel as the mouse wheel feedback. The issue here is with high resolution scroll wheels, whether that is a knob or a "frictionless" mouse wheel like on higher end logitech mice. What happens: You slowly rotate the scroll wheel while nothing is happens in firefox, then you get to a certain point and firefox scolls one step, then you continue to slowly rotate the wheel, and eventually firefox scrolls another step. What should happen: It continuously scolls as you rotate the wheel. This works in chromium browsers and other chromium based apps like discord, steam, etc, it also works in kde settings app, dolphin, okular, etc. But not firefox. It even works in terminal. Both firefox and thunderbird are like this. Is there a way to get this working or is it simply not supported in firefox? If so then feature request: get high res scoll wheels to work
