Firefox-based WebXR Viewer Brings Web-based AR Experiences to iOS

Mozilla has launched a serious revamp of its WebXR Viewer app on iOS, bringing assist for the newest model of the WebXR normal, which permits AR and VR experiences to run from the online on the iPhone and iPad.

Mozilla launched its preliminary WebXR Viewer app on iOS again in 2017. It was a easy developer-focused instrument that carried out Apple’s ARKit monitoring alongside an early model of the WebXR normal to assist web-based AR and VR experiences that may run immediately inside a browser. The app was basically a stopgap for builders to have the ability to check WebXR experiences on iOS units in lieu of the default iOS browser, Safari, which hadn’t carried out WebXR assist.

Quick ahead just a few years—throughout which period the WebXR normal has been quickly maturing and Apple hasn’t proven any curiosity in a Safari implementation—and Mozilla is forging forward with a extra strong model of the app which it calls WebXR Viewer

Whereas the unique app was a quite simple single-page browser the place you may paste a URL to load and check a WebXR expertise, the newest model is an entire rewrite of the appliance which is now based mostly on the Firefox iOS app. This implies the browser appears, feels, and behaves just about like Firefox on iOS—together with tabbed searching, historical past, personal searching, and so on—making it way more like an everyday brownser than the unique.

The WebXR Viewer additionally implements the newest model of the WebXR normal, which implies builders can work with the newest capabilities, together with some innovative experimental options that are nonetheless being fleshed out amongst these guiding the usual’s growth.

Whereas the app continues to be experimental, and principally designed as a testbed for builders, Blair MacIntyre, Principal Analysis Scientist at Mozilla’s XR staff, makes it clear that one key purpose for rebuilding the app with the Firefox iOS codebase is to check the WebXR implementation for potential future inclusion within the precise Firefox iOS browser.

Within the close to future, we’re inquisitive about persevering with to experiment with extra superior AR capabilities for WebXR, and seeing what sorts of experimentation builders do with these capabilities. Most AR use instances have to combine digital content material with significant issues on the planet; placing cute dinosaurs or superheros on flat surfaces on the planet makes for enjoyable demos that run anyplace, however genuinely helpful client and enterprise purposes have to sense, monitor, and increase “individuals, locations, and issues” and have content material that persists over time. Enhancing the Immersive Net with these talents, particularly in a “webby” method that provides privateness and safety to customers, is a key space Mozilla will likely be engaged on subsequent. We have to guarantee that there’s a standards-based answer that’s safe and personal, not like the proprietary options presently available in the market which can be siloed to create new, closed markets managed by single firms.


Towards this finish, we moved this implementation into the Firefox for iOS code-base to see how this strategy to implementing WebXR would behave inside Firefox, with a watch in the direction of (probably) integrating these options into Firefox for iOS sooner or later. Would the WebXR implmentation work in any respect? (Sure.) Wouldn’t it carry out higher or worse than within the outdated app? (Higher, it seems!) What UI and usefulness points would come up? (Loads.) Whereas there’s nonetheless loads of UI work to do earlier than shifting this to a mainstream browser, we’re fairly proud of the efficiency; WebXR demos run higher on this model of the app than they did within the earlier one, and the influence on non-WebXR net pages appears minimal.

Mozilla, it appears, has picked up the mantle of bringing a fully-featured browser with WebXR assist to iOS.

Whereas Apple had proven some assist for the older WebVR normal up to now, in recent times the corporate has been shifting in its personal route for web-based AR content material. Up to now that is largely restricted to the ‘AR Fast Look‘ performance which permits Safari to tug 3D fashions from a webpage and place them into an AR view with minimal interactive capabilities.

It’s a easily carried out characteristic, however extremely restricted in potential use-cases in comparison with WebXR, particularly as a result of it isn’t machine or browser-agnostic; it solely works on iOS units.

However, Mozilla has been centered on bringing open and safe AR and VR capabilities and platforms to as many units and browsers as attainable.
