This is why we should be checking for capabilities/features and not version. And part of this is reporting the correct, helpful error message when the capability isn't there, and not just say they have the wrong version.

I still have this problem with 64 bit flash on Linux, which adobe has decided to use a different format version string for.

It is checking for capabilities and not version: try { gl = canvas.getContext( "experimental-webgl") ; gl.viewportWidth = docWidth; gl.viewportHeight = docHeight; } catch(e) { } if (!gl) { alert("This website requires WebGL. Try running Chrome 9+ or Firefox 4+"); }
