How do I enable WebGL on my computer?

In order to find out if WebGL is enabled on your web browser, simply visit https://get.webgl.org/.

To enable WebGL on your computer:

Chrome: Type "about:flags" (without the inverted commas) in the address bar, then look for "WebGL" and enable it. 

Firefox: Type "about:config" (without the inverted commas) in the address bar, then look for "webgl.force-enabled" and switch it to "true". If you can find "webgl.disabled", switch its value to "false"
