Description:

I used to have the AUR package firefox-gtk3 in order to get in Firefox the "pixel perfect scrolling" made possible by GTK3. This package was removed in favor of the official firefox package when it moved to GTK3 a few months ago, but pixel perfect scrolling has never worked on the version provided by the official package.

Package version: firefox 44.0.2-2 (x86_64)
But this happens since the move to GTK3.

Steps to reproduce:

Using a Touchpad or TrackPoint (since a mouse scroll wheel doesn't have the required precision). Open Firefox and go to a website where you can scroll. Try to scroll with precision.
This task depends upon

What was different about your package that made it work?

This was an upstream change, see:
https://bugzilla.mozilla.org/show_bug.cgi?id=1170342
https://bugzilla.mozilla.org/show_bug.cgi?id=1207973

So, set MOZ_USE_XINPUT2=1 to reenable precise scrolling.
