I'm on LMDE 7 Gigi and use standard Firefox that comes with Mint. Recently I installed Librewolf via Flatpak and wondered why all the touchpad gestures like 2-finger-swipe for back/forward and pinch-to-zoom worked out of the box in Librewolf. When I looked that up it seemed that this only works with Wayland but not on X11. I guess this comes down to the installation via Flatpak?

Is there a way to get these gestures on Firefox under Mint? Or do I have to wait for Wayland support? I'd just use Librewolf with the gestures working but unfortunately I couldn't get my KeePassXC data bank synced. This might be because of Flatpak, I tried to manually set the sync folder but KeePass couldn't find a connection there.

Thanks!
