Sure! Do you have a local build of Firefox already? If not, you can find instructions [here](https://firefox-source- docs.mozilla.org/setup/index.html). As discussed in comment 4, we are initially only looking to change the value of the [apz.gtk.pangesture.delta_mode](https://searchfox.org/mozilla- central/rev/0b55b868c17835942d40ca3fedfca8057481207b/modules/libpref/init/StaticPrefList.yaml#593) pref, to 2 (pixel mode), and only on the Nightly branch. You can see an example of making a pref value conditional on Nightly [here](https://searchfox.org/mozilla- central/rev/0b55b868c17835942d40ca3fedfca8057481207b/modules/libpref/init/StaticPrefList.yaml#4539-4543). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1922047 Title: Touchpad scrolling is too fast Status in Mozilla Firefox: Confirmed Status in GTK+: Fix Released Status in Mutter: New Status in firefox package in Ubuntu: Confirmed Status in gtk+3.0 package in Ubuntu: Confirmed Status in gtk4 package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: This is an issue which has troubled me for a while. Anecdotally, scrolling feels way too fast in GNOME on Wayland compared to on X11. I finally tested it semi-scientifically, and it seems like GNOME on Wayland scrolls almost exactly 1.5x faster than GNOME on X11. I tested this by testing how many lines are scrolled from a full two- finger touchpad swipe from the bottom of my touchpad to the top of my touchpad, and logged a few attempts in both X and Wayland. I kept track of the results in this spreadsheet: https://docs.google.com/spreadsheets/d/17EaBM5Pgt7GdnnzcN2Vchk4kfT7IZ6i4qZ0zpVRGLhc/edit?usp=sharing I scrolled in one of my own GTK applications (https://github.com/mortie/lograt) because it lets me easily see how many lines I scrolled. Attach is a video of one full scroll on X11 and one full scroll on Wayland. This testing was performed on a Dell XPS 13 9343, but I've also used Ubuntu on a Dell XPS 9575 where GNOME Wayland scrolling also feels way too fast. I don't have other hardware to test on. This has been an issue on both Ubuntu 20.10 and Ubuntu 21.04.
