Any clues why this doesnt work in firefox?

[aseaofflames]

this script uses ajax to call a php script to rotate an image. My question is: why does it work in ie but not in firefox?

function rotate(filename) {
var degrees = prompt("Number of Degrees To Rotate:", "90");
if(degrees) { 
var ajaxRequest;  // The variable that makes Ajax possible!
	
	try{
		// Opera 8.0+, Firefox, Safari
		ajaxRequest = new XMLHttpRequest();
	} catch (e){
		// Internet Explorer Browsers
		try{
			ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try{
				ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e){
				// Something went wrong
				alert("Your browser broke!");
				return false;
			}
		}
	}
	// Create a function that will receive data sent from the server
	ajaxRequest.onreadystatechange = function(){

		if(ajaxRequest.readyState == 4){
		var rc = ajaxRequest.responseText.replace(/(<([^>]+)>)/ig,"");
		alert(rc);
		var host = window.location.hostname;
		var image = '<img src="http://"+host+"/thumbnail.php?gd=2&maxw=450&src=site/includes/images/temp/'+filename+'">';
		document.getElementById('image2').innerHTML = image;
			}
	}
	var php = "includes/rotate.php?file="+filename+"&deg="+degrees; 
	ajaxRequest.open("GET", php, true);
	ajaxRequest.send(null);
	} else {
	alert("Rotation Cancled");
	} 
}

anyone have any ideas?

Looks reasonable, what's the problem? I mean are there any error messages?

Please post a link to the page on your site that contains the problematic code so we can check it out.

its part of a file hosting site:

http://www.dropbox.uni.cc/site/

click login

credentials:
username: test
password: test

click my files (in menu on left)
click images (under limit)
choose an image and click manipulate
click rotate

a box shows up asking how many degrees to rotate, but after that, nothing happens in firefox
(like i said before, it works fine in internet explorer)
