Hi @298068845 , Thanks for attaching the error log! Sadly there is no error in the logcat (nothing that concerns the issue here). At least not one I can find. There are a few issues here:

  1. Due to security issues the browsers forces a user to actually enter VR using a user-event. AFAIK there is no way around that, but I am still looking.
  2. Another issue is in the playgrounds themselves - even thou chrome is perfectly fine with it, firefox is stricter when it comes to defining variables. Notice that vrHelper is not defined as a local but global variable (no "var" or "let") which can drive firefox ccrazy from time to time).

I am not closing this as I want to be 100% sure what I am saying is right, but I do believe that it is by design and not a bug.

So, did some testing. I sadly dont have a vive, but i do have an oculus rift, quest, and mixed reality. First for the positive results - in the quest's browser, it is possible to move from one page to another without exiting VR. This is rather self-explained - the quest's entire operating system is a VR OS. When using a PC and headsets, the situation is different. Edge will throw you out once a new website is loaded. Chrome will do the same. Fierfox, on the other hand, opens steamVR every time i use VR. So when moving to a new website, steamVR is presented and you have to actually click the VR button to load this experiment.

Thou i can"t find any documentation about it, it still seems to me like a security feature.

BTW - firefox reality browser for the oculus quest has completely crashed a few times, so i couldn't test with it. seems like a browser issue, need to analyse this further.

I am waiting for your input before closing this, please let me know if I understood it correctly.

I never heard quest，Is it linux system used for pc? Firefox reality browser for the vive quest has completely crashed a few times too,I think is browser issue, I try to feedback to firefox company but no respond.

The oculus quest - https://www.oculus.com/quest/ And note that i didn't say vive quest, i said oculus quest, which is the name of the headset. One can install a firefox browser in that system, and use it to browse the web and watch webvr content. I am not sure mozilla can really help with that (apart from finding out why the browser crashed), but as I wrote, this needs to be further analyzed. I hope this answers your original question. If it doesn't, please reopen the ticket.

Thank you for your help,I know firefox browser has bug.Oculus quest's browser is ok,Is it mean oculus rift's browser can do this?
