Configuração de Navegador/Integração de Diálogos com o Firefox

A partir da versão 64, o Firefox agora pode exibir as caixas de diálogo nativas do Plasma "Abrir" e "Salvar", integrando-se melhor à aparência do Plasma Desktop.

Aviso

Esse é um novo recurso e deve ser considerado experimental. Como tal, espere encontrar erros e relate qualquer um que encontrar: https://community.kde.org/Get_Involved/Bug_Reporting

Para habilitar os diálogos nativos:

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"

Warning

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