When I use Opera to open a site with WebGL, tells me that "This browser supports WebGL but it is disabled or unavailable". With Firefox I can use WebGL without problems...
I have already checked the options to enable WebGL in Opera.

Screenshots (Opera and then Firefox):

See if opera://gpu says that WebGL is enabled and if hardware acceleration is on.

Hardware acceleration seems disabled or not working for some reason and probably that's why WebGL is also not working.

Maybe I'm wrong, but I think so: if WebGL works in Firefox and not in Opera, the problem is Opera... in my opinion this is a bug or less functionality ...

@the-blinded is correct. I have a similar setup - latest version of Opera, latest version of Sierra, 2011 MacBook Pro. WebGL works in every other browser but cannot be enabled in Opera. This is a bug in Opera.

Not quite sure it's an Opera bug...
Latest version running under High Sierra:

I am using Opera 49.0.2725.39. I have MacOS 10.12.6. WebGL 1 & 2 both show as working for me. That is more than I can say about Safari and Pale Moon. With those browsers, WebGL 2 is not working.
