mm_menu.js HTML 5 Internet Explorer Mozilla Firefox

http://msdn.microsoft.com/en-us/library/ie/bg182625(v=vs.85).aspx

mm_menu.js is an output of Dreamweaver and enables drop-down menus. Microsoft is eliminating

document.all            and replacing it with                 document.getElementById

to comply with HTML5 standards

I modified mm_menu.js as Microsoft recommended (so I thought) and it worked perfectly well in Internet Explorer. However, I couldn’t get the drop-down menus in Mozilla Firefox. What do I need to do to get mm_menu.js to work or does Firefox need to make additional modifications? 

FYI, I tried using the following quick fix which resulted in the Internet Explorer page displaying incorrectly:

<meta http-equiv="X-UA-Compatible" content="IE=9"/>

It would be nice if the same javascript worked in both Internet Explorer and Mozilla Firefox.

Thanks,
