Firefox incompatible with demo

I just wanted to let you know that Firefox cannot run some of the demos (e.g. Maxit Single-Player or Safe Landing) because some of the JavaScript is used non-standard.

In the Maxit Single-Player demo, the <canvas> tag has onclick="clickMove()". This should be changed to onclick="clickMove(event)". This is because Firefox used the implicit event variable but, unlike Internet Explorer (and others), it does not define it as window.event.

In the Safe Landing demo, the charCode attribute is used incorrectly. As you are using jQuery, you can replace every occurence of charCode with which and replace the backspace block with

if (e.which == 8) {
    self.key(e);
}

Thanks in advance!
