Setup Instructions

  1. Download and launch Firefox Nightly.
  2. Download version 1.0.6 (64-bit) of the openvr_api.dll file from the OpenVR GitHub repository.
  3. Save the openvr_api.dll file somewhere on your computer where the user running Firefox can read it (e.g., c:\openvr\).
  4. In Firefox Nightly, navigate to about:config; change the value of dom.vr.openvr.enabled to true and gfx.vr.openvr-runtime to the full path of the openvr_api.dll file (e.g., c:\openvr\openvr_api.dll).
  5. Ensure that your Oculus Home settings allow for Unknown Sources.
  6. For PCs (especially laptops) using Nvidia chipsets, there are several methods of enabling the discrete GPU. One way is from the NVIDIA Control Panel: Load 3D Settings > Manage 3D Settings > Program Settings tab, and select Mozilla Firefox (firefox.exe) (with the blue Nightly icon) as the program to customize, and select “High-performance NVIDIA processor" as the preferred graphics processor.
  7. Restart Firefox Nightly.
  8. Enjoy WebVR content!
