On a related note, I develop libraries for embedding web browsers in Unity 3D (https://vuplex.com), including a library for embedding the Mozilla GeckoView library used by FireFox Reality. I plan to develop a WebXR driver for it, but haven't prioritized it yet. If you're interested in developing a WebXR driver for use with GeckoView (for example, to use with Oculus Quest), you can contact me, and I'll send you my notes from my research:

I'm interested in how you might be able to get through the CORS problem in WebXR/Browser standards ? In a VR Unity app with embedded browsers you can click through hyperlinks no problem but in WebXR the same hyperlink will trigger an origin mismatch and break out of immersion. Not having good 2D web content integration is a major blocker in WebXR for so many applications.

Hi, Jimmy . I think what you're saying is that when a new page is loaded, you want to avoid getting kicked out to the 2D view of the browser first (similar to switching between apps on Oculus Quest). I think there are opportunities to achieve that both at the web page level and at the browser level.

• At the web page level, an alternative to loading a new page entirely could be to load new content into the existing page, similar to a SPA. However, like you mentioned, that wouldn't really work if you want to seamlessly transition to a WebXR experience from a 3rd party. That's where browser-level innovation could come in:

• At the browser-level, it could be possible to come up with an innovative solution to this. For example, perhaps the user could grant a site permission to load the second site in a second browser instance and then transition from the first to the second once the second has loaded. This is kind of like allowing popups in a traditional 2D browser, where a page can create a new tab with window.open(), but with the additional capability of allowing the page to programmatically navigate to the new window once it has loaded.
