Firefox file dialogue is gtk on Plasma 5 Wayland

I switched to Wayland on Plasma 5.27 Manjaro Stable and Firefox can’t use Plasma “open file” or “save as”. Instead it uses gtk dialogues. In about:config I have

widget.use-xdg-desktop-portal.file-picker set to 2

widget.use-xdg-desktop-portal.mime-handler set to 2

When I set them to 1 dialogues don’t pop-up at all.

I have xdg-desktop-portal, xdg-desktop-portal-gtk, xdg-desktop-portal-kde packages installed.

systemctl --user status plasma-xdg-desktop-portal-kde

Make sure xdg-desktop-portal.service and xdg-desktop-portal-kde are running, then run:
GTK_USE_PORTAL=1 firefox

…and lose the xdg-desktop-portal-gtk - you’re using KDE, not GNOME.

Is needed for come theming things on wayland (or if using flatpak).

These should probably be 1.

See this section and the one directly below it.

Well, that’s disappointing.

The solution for me was to set xdg-desktop-portal in about:config to true and I created
~/.config/xdg-desktop-portal/portals.conf
with

[preferred]
default=kde

You just described life…
