Do you also know a possibility to stop inertial/kinetic scrolling on two-finger-tap / rightclick? (left click works, but since I scroll with two fingers, it would feel much more natural on rightclick)
No worries. That one is a little harder. My understanding is that libinput doesn't handle kinetic scrolling at all[0], it is now implemented at the toolkit level. For Firefox, the "hold" gesture to stop kinetic scrolling is blocked on either the required event being backported to GTK3 or Firefox being ported to GTK4[1].
My only suggestion for the time being is to try scrolling back a tiny bit in the opposite direction rather than tapping. Works for me, lol.
I can't thank you enough for pointing this out. Now (finally) my scrolling is acceptable on Fedora 36.
See https://www.reddit.com/r/Fedora/comments/qn0o9w/adjust_touch... for some further fedora specific instructions, but also read the instructions of the repository.
