WebVR is now only enabled for 64-bit builds.

Could you try updating to a 64-bit build and see if it fixes it?

Please note that a different regression in Nightly and Beta will cause corruption of the display on your 2d monitor while in VR in Nightly and Beta (Release is not affected).  You can work around this with a preference change:

layers.mlgpu.dev-enabled = false

When Bug 1381085 lands soon, you won't need this extra preference.

If you really need to stay on the 32-bit build, you can also manually enable WebVR still:

dom.vr.openvr.enabled = true
dom.vr.oculus.enabled = true

After
dom.vr.openvr.enabled = true
dom.vr.oculus.enabled = true

Does it fix the problem on FF 32 bit?
