Hello everyone, I’m new to NixOS and I’ve been having trouble trying to make firefox use Plasma 6’s native file picker. I have xdg-desktop-portal-gtk, xdg-desktop-portal-kde and xdg-desktop-portal all installed. widget.use-xdg-desktop-portal.file-picker is set to 1 in Firefox’s about:config. According to the NixOS wiki the setting in about:config is all that needs to be done for it to be used, but in my case it’s not working. I haven’t explicitly enabled any portal in configuration.nix and only followed the NixOS Manual for configuring flatpak (where it says things about portals, although I don’t know how relevant it is).
Thanks in advance for your time and any answer is appreciated!
When launching Firefox from commandline, I’m getting this output when trying to invoke the file picker:

I was able to fix it. Apparently, the NixOS Manual’s flatpak section says to add in configuration.nix:
{
xdg.portal.extraPortals = [ pkgs.xdg-desktop-portal-gtk ];
xdg.portal.config.common.default = "gtk";
}
The part that caused problems was xdg.portal.config.common.default. Commenting or completely removing this line fixes the problem.

I have the same issue. And I tried to fix it by removing
xdg.portal.config.common.default = "gtk";
but this did not work.
Any other ideas?
