One finger scrolling (touchscreen) in Firefox

I try to enable one finger scrolling in firefox ( it's more comfortable to scroll like that with a touchscreen). The default fedora version of firefox and chromium work like that.

I tried to launch firefox with the option MOZ_USE_XINPUT2=1 but it doesn't work.. Can you help me ??

I had similar issues with the HP Pavilion x360. I found that MOZ_USE_XINPUT2=1 only works in Wayland, not Xorg. Furthermore, to make it a permanent solution I needed to follow these steps:

1. open about:config in firefox to set dom.w3c_touch_events.enabled=1 (default is 2).

2. edit /etc/security/pam_env.conf and add MOZ_USE_XINPUT2 DEFAULT=1

3. reboot and restart firefox

I just might have the solution for you.

I was facing the exact same issue with Firefox where I could only scroll with two-fingers and single finger selected text.

After a lot of searching I found this Gentoo Wacom page mentioning that the Wacom driver has gesture emulation that causes a problem with Firefox and my Thinkpad X1 Yoga has a Wacom touchscreen.

The fix is to turn off the Wacom gesture setting by creating the following file:

/etc/X11/xorg.conf.d/50-wacom.conf

With this configuration:

Section "InputClass"
    Identifier "Wacom class"
    MatchProduct "Wacom|WACOM|Hanwang|PTK-540WL|ISDv4|ISD-V4|ISDV4"
    MatchDevicePath "/dev/input/event*"

    Driver "wacom"
    Option "Gesture" "off"
EndSection

Resart and enjoy :)
