  1. Download version 1.02 of the openvr_api.dll from the OpenVR GitHub repository. If you are on 64-bit Firefox download the 64-bit version; otherwise, download the 32-bit version. 64-bit Firefox is recommended for WebVR.
  2. Save the openvr_api.dll file somewhere on your computer where the user running Firefox can read it. For example, you could create a directory like “c:\openvr” and place the dll there.
  3. In Firefox Nightly, navigate to “about:config”.
  4. Change the value of “dom.vr.openvr.enabled” to “true”.
  5. Change the value of “gfx.vr.openvr-runtime” to the full path of the openvr_api.dll that was downloaded. For example, “c:\openvr\openvr_api.dll”.
  6. Restart Firefox Nightly.
