SeaMonkey private browsing

I prefer to have a separate menu entry to start my web browser in private mode. I have been using SeaMonkey for quite some time and I always did:

File > New > Private Window.

SeaMonkey can be started directly in private mode, by executing the program with the following option:

seamonkey -private

So, I made the following desktop file, named seamonkey-private.desktop:

[Desktop Entry]
Name=SeaMonkey (Private Window)
Comment=Web Browser Private Window
Exec=/usr/bin/seamonkey -private
Icon=/usr/lib64/seamonkey/chrome/icons/default/abcardWindow48.png
Terminal=0
Type=Application
Categories=Application;Network;

Save it to ~/.local/share/applications/ and it appears in the menu. It uses an icon that comes with the seamonkey package.
