I have just purchased a Rift S and had fun playing beatsaber. Unfortunately when I try to play with the firefox VR examples found here: mixedreality.mozilla.org
SteamVR starts and places me in the steam loading area. I can look around there but cannot see anything loaded. After a few seconds I get an report by steam saying that I dont have a configuration for firefox set. When I add a configuration for the rift controller it is never picked up. Does anyone know how to fix this or experienced it before?
