Could you please provide more details?

- What headset was being used (ie. Oculus or HTC Vive?)
- How long did you wait before it froze?
- Did refreshing the page correct it?

Thanks!

We have uplifted a number of stability fixes to Beta in the past weeks.  Please advise if this problem is still occurring.

Hello Kip! 

I used Oculus Rift, to fix this issue the user must restart the browser. 
The time until the freeze occurs is not constant, however an average would be 7 minutes.
Refreshing the page causes the VR device to remain in a closed status. 

Are the stability fixes available in Fx 55.0b12? 

Thank you!

@larsberg mentioned that this may be a WebAudio related leak.

IMHO, this should not block WebVR in 55, but should be investigated further.

I re-tested using Fx 55.0b13 and the issue is no longer reproducible.

Cheers!

I re-verified using Fx 57.0b5 and Fx 58.0a1 (build ID: 20171004100049) on Windows 10 x64 and I can confirm this issue is fixed.
