Firefox 55

Firefox 55 brings Virtual Reality to your browser after 23 years of wait

So, all you need to do is connect your compatible VR headset, including HTC Vive and Oculus Rift, and experience virtual reality without installing any custom apps to do the same.

Well, Chrome and Edge already have WebVR support with some limitations and Firefox is not the first to be capable of running VR content. But, Mozilla says Firefox is the first desktop browser to have support for WebVR.
