it's annoying for me too. The problem is that setting the envar just
substitutes some problems with different ones:
- Without this envar set, there is no touchscreen scrolling, and touchpad
scrolling goes three lines at a time rather than pixel-by-pixel
- With this envar set and a notification appears, touchpad scrolling is
interrupted and mouse wheel scrolling stops working entirely until Firefox is
de-focused and re-focused
The correct solution is to fix these bugs, not toggle between two broken
states. Chromium has different scrolling bugs, BTW.

Title:
Package Firefox with MOZ_USE_XINPUT2=1 in environment to enable pixel
scrolling with touchpad and touch gestures
Status in firefox package in Ubuntu:
Invalid
Bug description:
Ubuntu version: Kubuntu 17.04
Firefox version: 53.0.3+build1-0ubuntu0.17.04.2
In Firefox, two-finger scroll gestures on a touchpad are interpreted
as scroll wheel rotations, and the content scrolls three lines at a
time. This is inappropriate behavior for touchpad scrolling; it should
scroll pixel-by-pixel.
Firefox already has the ability to do this, you just need to turn it
on by running the program with MOZ_USE_XINPUT2=1 in the environment:
for example, by running `MOZ_USE_XINPUT2=1 firefox`, or adding it to
/etc/environment or something like that.
Turning on this behavior yields a large usability improvement for
laptop users. Therefore, I am proposing that MOZ_USE_XINPUT2=1 be
permanently added to the packaging such that it's always present when
Firefox runs. This is what Fedora does, and it results in a much
improved experience for the laptop user.
