Prevent Firefox Adverts Opening SteamVR

I have a HTC Vive and lately when browsing various sites including engadget & Tom’s Hardware I notice SteamVR keeps opening.  Turns out some dickhead advertisers are trying to force VR ads on me.  The problem is I work with lots of Firefox tabs open across 3 screens and when you try to close SteamVR it also wants to close Firefox.  The solution is pretty simple, just disable VR in Firefox:

  1. Type about:config in the address bar
  2. Type VR into the search box at the top of the config page
  3. Double click both “dom.vr.enabled” and “dom.vr.openvr.enabled” so the right side value column says “false”

Done.  It’s a bit of a pain if you do any browser based VR work but you can always re-enable it while working and turn it off again afterwards.
