Starting with version 64, Firefox can now display the native Plasma "Open" and "Save" dialogs, thus integrating better with the look and feel of Plasma Desktop.


This is a new feature, and should be considered experimental. As such, expect to find bugs, and please report any you find:

To enable the native dialogs:

  • Install the necessary libraries. On most distributions, this can be done installing the xdg-desktop-portal package. This may be broken into two separate packages, xdg-desktop-portal and xdg-desktop-portal-kde.
  • Make a copy of the Firefox desktop file:
    cp /usr/share/applications/firefox.desktop $HOME/.local/share/applications
    If this feature is desired for all users, the system-wide shortcut must be modified as a user with superuser (root) privileges
  • Using the kwriteconfig tool in a console window (or a text editor), modify the Exec directives to instruct Firefox to use the Portal functionality.
    kwriteconfig5 --file $HOME/.local/share/applications/firefox.desktop --group "Desktop Entry" --key "Exec" "GTK_USE_PORTAL=1 /usr/lib/firefox/firefox %u"
    kwriteconfig5 --file $HOME/.local/share/applications/firefox.desktop --group "Desktop Action new-window" --key "Exec" "GTK_USE_PORTAL=1 /usr/lib/firefox/firefox --new-window %u"
    kwriteconfig5 --file $HOME/.local/share/applications/firefox.desktop --group "Desktop Action new-private-window" --key "Exec" "GTK_USE_PORTAL=1 /usr/lib/firefox/firefox --private-window %u"


Changing all "Exec" directives is required as Firefox can be started in multiple modes.
