Under unity, gufw is displayed under 'other' in system settings. However under gnome-shell and gnome-classic it is not displayed at all. So the only way to launch it is from the command line.
1. Under gnome-shell goto system settings
2. firewall is not displayed
None. Just updating the desktop file so it can display in GNOME.
