Plugin only working on Chrome (desktop & mobile) and Safari (mobile)

[svenjanser]

Hi Jeremy,

I have a problem with the plugin concerning browser compatibility.
Displaying 360-degree images works just fine in Chrome & Safari, but on FireFox (Version 61.0.1 "Quantum"), Microsoft Edge or Microsoft Internet Explorer.

It just displays "loading" in those browsers after clicking on the loading-link.
I tried different approaches like autoload, same problem.

Image size is 10000px x 5000px, filesize 3.5 to 5.5 MB.

Is there any problem perhaps with the canvas implementation cross browser?

Thanks in advance!
Greetings, Sven
