Your moving picture is using all CPU time, leaving none for other functions.

can you pls. tell me where is the error why the zindex + javascript not working in mozilla

Well as midimagic said "your moving picture is taking up all the cpu time" that will cause the site to slow down majorly and possibly make your zindex and javascript not work.

I don't think that this is the problem because it is working very well in IE but its not working in mozilla

actually your main problem is "double floating" with your float coding.

try instead of:

onmouseover="menu_visible(hiddenmenu)" onmouseout="menu_hidden(hiddenmenu)"

this

onmouseover="menu_visible('hiddenmenu')" onmouseout="menu_hidden('hiddenmenu')"

i know it might sound farfetched but given my experience in x-browser programming, even the smallest thing matter and are pesky

and of course

instead of

function menu_visible(menu)
	{	
		menu.style.visibility="visible" 
		menu.style.cursor ="hand" 
	}

try

function menu_visible(menu)
	{	
		document.getElementById(menu).style.visibility="visible" 
		document.getElementById(menu).style.cursor ="hand" 
	}
