1381760 - Firefox treating touch input as mouse rather than touch input

Status: NEW

(Core :: Widget: Gtk, enhancement, P3)

Description

[Jean-Yves Avenard [:jya]]

Using a Dell XPS 15 9560 laptop, the touchscreen is unusable in Firefox.

If you manage to scroll, it scrolls opposite to what your hand gesture is doing (e.g. you move your finger up, but the screen scrolls down).

Otherwise, it will act like a mouse with the shift key pressed (e.g. it selects the text you move your finger on).

Using Chromium, the hand gestures work naturally as expected...

This post https://askubuntu.com/questions/858559/touschscreen-acting-like-mouse-ubuntu-16-04-on-dell-xps-13 indicates that the problem is app related, and that could be worked around with an addon.

But surely, it should work out of the box, just like Chromium does.

Microsoft has a fantastic blog post describing the perfect way to handle this on Windows: https://blogs.windows.com/msedgedev/2017/03/08/scrolling-on-the-web/ 

Firefox should ideally handle input the way Edge does.

This should work these days in Wayland mode, and in X11 mode with MOZ_USE_XINPUT2=1 in the environment.
