Oculus Rift will display "Please Wait", nothing happens. display won't connect to the oculus Rift but head tracking works.

Thanks in advance.

Hi, could you please retry again with the latest Firefox Nightly (https://nightly.mozilla.org/) builds and provide a sample URL? Thanks!

I'm on the latest nightly as of 11/6/2016

I believe that is because we are working on GPU process, and it breaks the Oculus support. I can reproduce it in e10s mode, and non-e10s is good. Please have a look at Bug 1316279.

For the record, I can confirm that disabling e10s works. I am able, for the most part, to launch a WebVR session using reasonably recent builds of A-frame. This is pretty buggy though, as the browser frequently forgets that the Oculus is available and enters Full-screen mode instead. Empirically, if I shut down FF. restart Oculus Home, activate the HMD by looking at the Oculus Home app, then re-launch FF, I am able to restore function. I'm not qualified to guess what, but it seems like some key process gets reset by this set of actions.

I'm also experiencing this exact issue, however disabling "Enable multi-process Nightly" does NOT resolve the issue for me.
Went through the usual (make sure external sources allowed, restart computer, restart oculus, restart firefox) steps and it's still not working.

For what it's worth, I haven't been able to get the Chrome developer build to work either.

Does anyone have debugging steps I can try to get it working?

Does setting security.sandbox.gpu.level to "0" in about:preferences and restarting the browser solve your issue?

If so, this should be fixed by Bug 1361719, which will be landing in a couple of days.

Otherwise, could you share a web site that this is failing on?
Also, please try this site and let me know if it behaves differently:

Correction:

about:preferences -> about:config

I just had this issue with https://edorble.com/webvr and an Oculus.

It goes to full screen mode when I click the VR button, but it doesn't go stereoscopic.

This issue seems to pop up again in Firefox 57. The Oculusshows tracking on the PC's screen, but not on the Oculus's display itself. 

Downgrading to Firefox 56 seems to solve the issue.

I've been able to mitigate this issue on my Oculus Rift by launching SteamVR manually before launching Firefox and navigating to a WebVR page.

I reproduced this issue using nightly 51.0a1 (build ID: 20160814030203). This issue is no longer reproducible using Fx 62.0.3, Fx 63.0, Fx 64.0b3 and Fx 65.0a1.
