Ако си с лисика и работиш с джаваскрипт, натискай ctrl+shift+j. Ще ти излезе JS ерор конзолата и ще те насочи към грешката ти :)
Ето така бачка при мен:
Код: 
	<div id="loadmsg" onkeyup="keyup(event.keyCode);" style="width: 100px; height: 100px; border: 1px solid red;"> <div id="loadwindow" onkeyup="keyup(event.keyCode);"  style="width: 100px; height: 100px; border: 1px solid red;"></div></div> 
	
	<script>
	
	var waittime = 100;


	var xmlhttp = false;
	var xmlhttp2 = false;

	function ajax_read( url ) {
	    if ( window . XMLHttpRequest ) {
	        xmlhttp = new XMLHttpRequest();
	        if ( xmlhttp . overrideMimeType ) {
	            xmlhttp . overrideMimeType( 'text/xml' );

Видях грешката при моя код . не е зададен loadwindow но интересното е че само при мозила прави тази грешка . нито при хрома нито при IE 8 има грешка .
