Firefox does not use default file manager

grep -rl Name=org.freedesktop.FileManager1 /usr/share/dbus-1/services
sudo mv /usr/share/dbus-1/services/org.xfce.Thunar.FileManager1.service ./

abrir o firefox e o gestor de ficheiros nos downloads e depois:
sudo mv org.xfce.Thunar.FileManager1.service /usr/share/dbus-1/services/org.xfce.Thunar.FileManager1.service
