WebGL not showing in Firefox (version 56) Android (6)

As mentioned in subject line, webgl is not showing in firefox android. It is fine in other android browsers.

Here are console errors.

Here is the Link

Can anybody please point me out what is the issue.


I opened the link in firefox in galaxy s8+, the task is fine there.
I think the issue is in low-spec models of phone/tablet.
Thanks for you time and quick reply.

You can try forcing to use WebGL 1 as the errors seem to relate to WebGL2.
