Hotspot example doesn't work on Edge + Firefox

[rich2701]

On Microsoft Edge (41.16299.15.0 tested) and Firefox (58.0.2 (64-bit) tested) the live vrview hotspot example available at (https://googlevr.github.io/vrview/examples/hotspots/index.html) does not work. The app crashes on load and leaves the user with an unending loading screen. The same pages works perfectly on Chrome and mobile browsers. The vrview hotspot implementation I have on my own website fails in the same way. I have not been able to work out why this is failing.

I can extend this to none of the examples under (https://googlevr.github.io/vrview/examples/) work in Firefox or Edge. The simple 360 image on the vrview developer page (https://developers.google.com/vr/develop/web/vrview-web) also does not work at all on Firefox.

I figured out in firefox, if you go to about:config and change the dom.vr.enabled to false the 360 image will show up. Asking end users to change the config in firefox is not ideal. Is there a way to make it work in firefox without making the config change?
