And Mozilla is working to ensure the web extends to these virtual realms. We already use the web for exploring, so using the web on AR and VR is a natural fit to some degree. But it takes a lot of work to build a web that people can use with pointers and hand gestures. Web developers still are struggling to adapt to phone's smalls screens and touch interfaces, so there's no guarantee the web will thrive in AR and VR.

"This prototype of Firefox Reality for HoloLens 2 will ensure that the immersive web works for all users, regardless of device they are on," said Lars Bergstrom, director of engineering for Mozilla's mixed reality group, in a blog post Monday. "Building on Microsoft's years of experience with the current HoloLens, we will work together to learn from developers and users about bringing AR content to the web."
