VR presentation in Firefox on the Vive kicks out repeatedly with `(unresponsive) firefox.exe` error

[cvan]

When playing A-Blast in my Vive headset, I've noticed (more recently in Firefox 55+) that if I move around, every few seconds, I am dropped out of VR. And Steam VR shows the common error: (unresponsive) firefox.exe.

I'm kicked back into the Steam VR "Big Picture" menu. But then after a second or two, VR presentation returns, and I'm back in A-Blast.

In my recent testing, I haven't experienced this in too many other demos (only a handful of times in other A-Frame experiences). Are there any significant heavily performant tasks being done that could be causing this? If you have hunches that this is a Firefox issue, let me know, and I'll file a Gecko bug. /cc @kearwood

So, i managed to solve my issues.
I'm not sure if you need to do both of these.

1. Enable hardware acceleration in Firefox settings.
2. upgrade Firefox to 64-bit.
   after that. it started working for me.
