User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

I opened the Firefox flatpak in a Wayland window (with --env=MOZ_ENABLE_WAYLAND=1 --socket=wayland options enabled).

Actual results:

The XDG file chooser portal doesn't work. I only have access to the Downloads folder, since it's the only directory enabled in the Firefox flatpak.

Expected results:

The file picker should work and should allow me to see everything my filesystem has.

Could not install Firefox Flatpack on my Ubuntu 20.04 machine, assigning this to the Widget: Gtk component so that someone with more knowledge in this area can take a look.

I think this is intended behavior, what do you think Jan?

Looks like we're wrongly detecting flatpak environment we should use https://gitlab.gnome.org/GNOME/gtk/-/blob/4300a5c609306ce77cbc8a3580c19201dccd8d13/gdk/gdk.c#L472 - filename changed from flatpak-info to the .flatpak-info

No it is not intended. It is supposed to let the user pick contents from any directories from the XDG file portals, despite only being limited to xdg-downloads:rw. This works when opening Firefox in an X11 window but not when opening Firefox in a Wayland window.

We're wrongly detecting that we are in the flatpak environment Setting widget.use-xdg-desktop-portal (as a workaround) should fix it for now. I'll attach the patch in a few.

Can you show me how I can do it? I will appreciate it.

Go to about:config page, look for widget.use-xdg-desktop-portal value and set it to true.

Looks like it worked. Thank you!

Do I close this issue or do I keep it opened?

Running the FF85 beta as a Flatpak on Fedora (33) Silverblue, I'm unable to get application links to open (e.g. Zoom)

Go to about:config page, look for widget.use-xdg-desktop-portal value and set it to true.

This doesn't seem to change the behavior

We're sorry, but because of the bug 1669282 the application links has been disabled in the flatpak because there's no workaround for this problem.

The problem lies with the update process sometimes.
there are user units in systemd called:

• xdg-desktop-portal
• xdg-document-portal
• xdg-desktop-portal-gtk
• xdg-permission-store

Reload those via systemctl --user daemon-reload

this fixes the problem.
