Menu
Whenever I click on the checkbox, the browser window (firefox) will scroll on the top of the screen.
How can I prevent this behavior so when I click on the checkbox the browser window will not scroll on top?
Here is the code found from here http://jsfiddle.net/zAFND/6/
Thank you.

To stop a web page from scrolling to the top when a link is clicked that triggers JavaScript, we call preventDefault in the link's click handler.
The problem is this rule:
#ck-button label input {
position:absolute;
top:-20px;
}
When you click on a label the browser tries to focus the related input. In your case the checkbox element is lying at the top of the page, even outside the viewport – so Firefox tries to scroll there.
You can solve it like this by adding:
#ck-button label {
display: block;
position: relative;
overflow: hidden;
}

Alternative
Heisenberg points out a problem in his answer which can occur when using extreme values. Unfortunately the proposed idea has the same quirk as the one shown above.
So an alternative solution is simply to hide the input. The functionality is not affected.
CSS
#ck-button label input {
display: none;
}
