Virtual reality is all about immersing yourself in a made-up world that looks (in theory) like you’re really in it. The last thing you need is a flat floating rectangle that shatters that illusion. That said, if you ever need to access the Web, that’s exactly the only way. Mozilla, however, says it doesn’t have to be a painful and disconcerting experience. With Firefox Reality now in its version 1.0 stable release, one of the world’s biggest web browsers is taking a step towards blending the 2D web and the immersive web.
