Will be awesome if D3D11.1 stereoscopic rendering mode can be added as a VR backend.. as similar to Oculus and other HMD requires two views all work done for VR can be also useful for stereo rendering..
also as Firefox for Windows uses ANGLE which uses D3D11 backend already wouldn't require much work..
D3D stereo rendering requires Windows 8 and up and all current GPUs and "consumer" stereo displays such as HDMI 1.4 3D TVs for example support it.. as said AMD,NV and Intel GPus support it.. and via this API also Nvidia 3D Vision monitors are supported and AMD HD3D monitors..
For a simple example using Stereo API see:
