WebGL issue

[be4zad]

My GPU is old and doesn't much support GL related things. so the website doesn't show the barcode and this error appears in the console:

Failed to create WebGL context: WebGL creation failed: 
* tryNativeGL (FEATURE_FAILURE_EGL_NO_CONFIG)
* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)

My browser is firefox and the issue may solve by:

• Enabling hardware acceleration
• Toggling webgl.out-of-process in about:config (worked for me)
• Toggling webgl.force-enabled in about:config

It's good idea to handle the error and suggest to user to try above suggestions.

Yeah, error handling should be better. At the very least it'd be good to report the WebGL creation failed part back.
