Bug Description

Firefox does not scroll with the usual touch gesture of swiping up or down on the screen. This action just selects text on the page as though the left mouse button was depressed and the cursor moved across the page.

lsb_release -rd
Description: Ubuntu 22.04 LTS
Release: 22.04

Snapstore version 103.0-1 latest stable

Possibly related to being packaged as a snap (have noticed this behaviour on Fedora using the firefox snap).

It's still possible to scroll by dragging the scrollbar but this essentially breaks firefox on touch systems

Thanks for the report.

Can you observe the problem if you run the firefox snap with MOZ_ENABLE_WAYLAND=1 ?

I'd "fixed" this bug long term by switching to the deb provided by Mozilla however ubuntu 22.04 recently decided to replace my deb install with the snap for no obvious reason so I just wanted to add that touch scrolling is still broken on the current snap.

Is there no prospect of fixing this? It seems like "MOZ_ENABLE_WAYLAND=1" should probably be the default... since wayland is the default on current Ubuntus.

TBH, it seems a little crazy for Ubuntu to depend on a browser packaged by a third party like this. How is ubuntu supposed to get stuff fixed in Firefox if Mozilla aren't interested?
