It is indeed a common complaint/request as evidenced by the people talking about it in various places (blogs, reddit, etc.): https://www.rojtberg.net/1569/switching-back-from-chrome-to-firefox/ https://www.reddit.com/r/linux/comments/72mfv8/psa_for_firefox_users_set_moz_use_xinput21_to/ https://hackido.com/2019/02/01/2019-02-01-firefox-with-touch/
I paste here again the upstream bug report as the link changed slightly: https://bugzilla.mozilla.org/show_bug.cgi?id=1207700 Recent comments in it (a year old) are fairly positive: "I think we can enable the XInput2 for recent Gtk+ versions (say Gtk+ >= 3.20) as the related Gtk+ focus bugs was fixed but for XInput2 only. Also Fedora enables XInput2 by default and we don't have any user complains." However there is a list of possible issues that need to be checked before moving on this: https://bugzilla.mozilla.org/show_bug.cgi?id=1182700 (wheel scrolling issue when window not active) https://bugzilla.mozilla.org/show_bug.cgi?id=1390795 (wheel scrolling issue when window not active) https://bugzilla.mozilla.org/show_bug.cgi?id=1487882 (pdf zoom increments by 10%) https://bugzilla.mozilla.org/show_bug.cgi?id=1196777 (probably fixed) https://bugzilla.mozilla.org/show_bug.cgi?id=1170342 (fixed) Additionally, we need to check it works adequately when the synaptics driver is enabled (I'm not sure but perhaps it's enabled by default on Macbooks?). Finally, I tried a couple more tweaks in about:config to make the scrolling experience smoother with a touchpad: - disabling smooth scrolling: general.smoothScroll = false OR - enabling msdPhysics scrolling: general.smoothScroll.msdPhysics.enabled = true I'm not yet entirely convinced by either and still have to test it more, especially with a mouse. ** Bug watch added: Mozilla Bugzilla #1207700 https://bugzilla.mozilla.org/show_bug.cgi?id=1207700 ** Bug watch added: Mozilla Bugzilla #1182700 https://bugzilla.mozilla.org/show_bug.cgi?id=1182700 ** Bug watch added: Mozilla Bugzilla #1390795 https://bugzilla.mozilla.org/show_bug.cgi?id=1390795 ** Bug watch added: Mozilla Bugzilla #1487882 https://bugzilla.mozilla.org/show_bug.cgi?id=1487882 ** Bug watch added: Mozilla Bugzilla #1196777 https://bugzilla.mozilla.org/show_bug.cgi?id=1196777 ** Bug watch added: Mozilla Bugzilla #1170342 https://bugzilla.mozilla.org/show_bug.cgi?id=1170342 ** Bug watch added: bugzilla.opensuse.org/ #1032003 https://bugzilla.opensuse.org/show_bug.cgi?id=1032003 -- 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/1697122 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: Confirmed 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.
