Similarly to what they have recently done for NFL teams and for supporting Paris, Facebook have today launched a feature whereby users can add a lightsaber (either a blue Finn/Jedi blade or the Kylo Ren hilted red design) as a filter on their profile picture to show their excitement for the new Star Wars: The Force Awakens which will release in a couple of days.
In order to access this feature, simply visit this page and use the widget to add a lightsaber. It’s very simple, and soon you can be as cool as these guys!
