Default scrolling in Firefox (F30)

[Lukas Zapletal]

Hello,

I recently upgraded my laptop (X1 6th gen) and I am trying out Gnome on Wayland with all the default settings. Everything is superb, except two-finger scrolling in Firefox. It looks like it has different scrolling behavior than other applications.

Now, it's difficult to describe what I feel, but ramp-up time of scrolling is quite slow and feels like there is a lag. Then actual scrolling (using two fingers) is a bit fast (too much content scrolled) and finally when I remove my fingers then the decay time is a bit fast. I would like to feel more of like iPad.

I know I should be asking on Mozilla lists, but I think this might be also Wayland, libinput or touchpad driver related so trying here. Which settings should I tune to make this experience more closer to Safari on MacOS? Am I searching for about:config settings or some other settings in Fedora?

I tried the kernel setting psmouse.synaptics_intertouch=1 but no difference. Tried to play around in Gnome settings without luck. And finally spent some time fiddling with about:config values but there are so many combinations and documentation is almost zero. No surprise I came to zero conclusions.

Thanks for sharing your experience with that. I use trackpoint for work but I like touchpad for casual browsing in the evening (Twitter etc :-)

You are probably not using the Wayland version of Firefox, so it is 
going through the XWayland server.  Hopefully someone else can explain 
how to start it the right way.  There is a announced change for F31(?) 
that will switch Firefox to use the Wayland backend by default.

I did not change anything, so very likely.

Out of curiosity, does Firefox on Wayland provide smoother experience related to scrolling?

I've never tried it, but I assume it would be similar to other native 
Wayland apps.

It looks like if you install the firefox-wayland package, you should get 
a new launcher for it.
