It's with a touchpad, on a Dell XPS 13 9370 (a pretty well supported laptop on Linux).
I'm not sure it's a hardware related issue, as smooth scrolling does work well with regular gtk apps and it also works will with Firefox on a Fedora USB live session. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1870776 Title: No smooth scrolling on Firefox (and Chrome) Status in firefox package in Ubuntu: Incomplete Bug description: I'm on Ubuntu Beta 20.04 and I observe that smooth scrolling is not working in Firefox or Chrome, while it works well in other apps, like Nautilus/Files GNOME settings or within GNOME shell applications listing. I tried with Firefox in safe mode (so without any extension) with the same result. I also tried with a completely new GNOME user account (without any customization), with the same result. While I'm not so used to Chrome, it seems that smooth scrolling is not working with it either. Another test I did is to boot from a Fedora Workstation 32 Beta USB stick (with GNOME) and the smooth scrolling was working well in Firefox.
