The scrolling code itself should work in both IE and Mozilla (I'm not sure where the five ***** came in though - was that the UBB?), but instead of checking for document.all, which is only supported by IE, you should check for document.getElementById in the if statement.

What you probably want to do, is use window.scrollTo(x,y), where x and y are the position of the element on the page.

The following functions can get the x and y positions of an element on the page:

function getLeft(theelement)
{
if (theelement.offsetParent) return theelement.offsetLeft + getLeft(theelement.offsetParent);
else return theelement.offsetLeft;
}
function getTop(theelement)
{
if (theelement.offsetParent) return theelement.offsetTop + getTop(theelement.offsetParent);
else return theelement.offsetTop;
}

Use them as follows:

var scrolltoelement = document.getElementById('tester');
window.scrollTo(getLeft(scrolltoelement),getTop(scrolltoelement));
