webxr-samples VS webxr-linux

https://immersive-web.github.io/webxr-samples/ shows VR and AR supported, the demos (https://immersive-web.github.io/webxr-samples/immersive-vr-session.html) show the enter VR button but when I click it the button shakes and temporarily fades out. When the browser isn't configured correctly it says no VR detected

In that case I would start here: https://immersive-web.github.io/webxr-samples/ use something 90%+ ready to go.

I've scrolled through so many Microsoft Support pages but none of them are yet to work, so I thought of coming here to get a solution. So basically, I want to watch a Youtube VR video on Microsoft Edge and when I click the headset, a pop-up asks me if I want to allow Youtube to use my headset. I allow it, and on my headset, it shows that startup screen whenever you start up an application in VR, and once it fades in, I'm still have the Microsoft Cliff House. I've tried using Edge Canary and the other version but to no avail. I even tried running various WebXR samples, but whenever I start them up, the button that shows "Exit VR" goes back to "Enter VR" 0.5 seconds later. This leads me to believe that every single WebXR content doesn't work at all. If you have any fix to this, please tell me in the replies and suggest some cool WebXR websites for me to try. Thanks!

In your PICO 4, Does this work for you with AR & VR? https://immersive-web.github.io/webxr-samples/

However, when I try to view WebXR content on browsers (Chrome, Firefox, Opera), none of them show the permissions prompt and just says "VR Not Found". The WebXR part on the browser is working, https://immersive-web.github.io/webxr-samples/ says " Your browser implements the WebXR API and may be able to run Virtual Reality or Augmented Reality experiences if you are using a supported OS and the appropriate hardware." but below that no VR or AR device is detected even though my Vive Pro Eye is up and running SteamVR.

I know Edge and Firefox support WebXR (but WebVR is dead I think) and I was able to Enter VR on some example sites like https://immersive-web.github.io/webxr-samples/ while SteamVR was running. But the Youtube site offers no such thing anymore.

This can be seen here, or you can view the source here

Google pixel 3, android 12 https://immersive-web.github.io/webxr-samples/ has all checks ✅✔️✔️ so I'm unsure what is wrong.

I don't have any XR devices on me atm, but the WebXR Sample page suggests AR is supported, which afaik is the same as MR.

AFrame doesn't work on Linux, because no web browser on Linux supports WebXR. Your best bet is an unofficial firefox patch.

For that I have https://github.com/mrxz/webxr-linux in mind. I've done it on desktop (which sadly didn't work, using an NVIDIA rather than AMD GPU) but the process was less painful than expected, namely a bit of time to download then just 30min or less to compile the first time.

Just to be sure, you did change the preferences in `about:config` as listed here and restarted Firefox afterwards? I should probably update the patch to change the default values of these properties as well.
