It was bugging me for some time now that Sketchfab keeps starting SteamVR for no reason. As soon as a Sketchfab view is open anywhere SteamVR gets launched, when I then close SteamVR it gets instantly started again.
Now recently things got worse with it completely freezing my browser so that I have to force close firefox in the task manager.
I’m using Firefox on a Win7 PC. I also have start Steam VR with applications turned off.
