to desktop file to have it also support KDE dialogs.
For Maintainer
To test, go to a webpage and do CTRL+S. It will open up KDE file chooser after you use GTK_USE_PORTAL=1
.
For Quick Workaround for End Users
Open up firefox.desktop

Exec=env UBUNTU_MENUPROXY=0 /usr/lib/firefox/firefox %u
Change it as:
Exec=env GTK_USE_PORTAL=1 UBUNTU_MENUPROXY=0 /usr/lib/firefox/firefox %u
