To reproduce: Firefox, about:config, set webgl.disabled to true, load WikiDaheim.

@reiterbene Is this something that's easily fixable?

Unfortunatelly the error is triggered inside of the mapbox-component. But I will have a look if there is any other way to determinate if mapbox has loaded successfully.

As all modern browsers are capable of webGL I think it is not necessary to add a warning anymore. @simon04 , @BraveheartWikimedia ?

Would agree with that.
