WebGL JS errors in console

hi all
i just buld another sample project in webgl and wen to firebug console and i see JS errors.
Wante to check in to see how critical are they?

Our project (real one) will have lots of JS interactions so i wanna make sure we dont have issues with Unity internal JS having errors

tnx a lot

print: (function() {
return function(text) {
console.log (text);
};
})(),
printErr: function(text) {
console.error (text);
},

In your Module configuration, you can change these functions and it should be a bit more silent.

how do i do that?
Also disabling output does not necessary mean that problem is solved though
