CoSpaces use with HTC Vive

I know there was a thread on here earlier about CoSpaces and the HTC Vive. I read those and we followed the directions in the Tech Check. I was wondering if anyone had run into this issue or had any suggestions; we are getting the error that Firefox is unresponsive in STEAM VR. We have the most up-to-date version of Firefox and STEAM VR is updated. Thanks for any help.
