Chromium engineers have implemented an API called nanosecond API (available on Chrome v116) that significantly improves the fluidity of animations when scrolling in Chrome for Android. The suggestion is that Firefox for Android engineers investigate whether the patch is applicable to Firefox as well. The improvement will be noticeable for users with a 90hz+ screen.

Thank you Firefox engineers for your hard work! ❤️
