Mozilla has been working on VR for a while now, with support for Oculus Rift in the Firefox nightly builds as far back as 2015. Currently announced at the end of July and set to start rolling out live on August 8th, the latest version of Firefox (55) is set to include WebVR, the technology that puts virtual reality into a web browser. This addition will bring Firefox up to par with both Google Chrome and Microsoft Edge, which added web-based VR support in February and April of this year, respectively.
