The OP's site wasn't selecting standards mode, which is difficult to
support for the purposes of setting a div's position. Mozilla
requires a string parameter, including 'px', while Netscape 4 at
least, requires an integer.
The CSS units problem is not at all difficult to handle:-

OK, but another pitfall is that Mozilla doesn't update
document.docume ntElement.scrol lTop, so it's just as well that
window.pageYOff set is still available as it must be used instead.
