FCKeditor v2.5 problem with firefox 2.0 using php

Hi all,

I've been using FCKeditor for nearly 3 years and compared to some of the other wysiwyg's out there this is in my humble opinion by far and away the best, and makes managing website content so much easier

I've been trying to upgrade from one of the early versions today to the latest version of 2.5. IE works fine all of the plugins we've installed over the years work fine, however for some reason i can not get v2.5 to work in firefox.

What I get is the contents of the "Style" drop down menu appear where the top left hand corner of the wysiwyg should appear. I then also get a White box (meeting the height dimensions of the wysiwyg iframe) off the right of the sreen by a good 150px - 200px. - I get no content, no tool bars, not even an outline around the frame.

As i run firebug i've used that and it is saying there is an error on line 67 of fckeditorcode_gecko.js which it implies is related to the fckstyles.xml file the contents of which appear in a table.

Line 67 contains the following code:

 67FCKXml.prototype={LoadUrl:function(A){this.Error=false;var B=this;var C=FCKTools.CreateXmlObject('XmlHttp');C.open("GET",A,false);C.send(null);if (C.status==200||C.status==304) this.DOMDocument=C.responseXML;else if (C.status==0&&C.readyState==4) this.DOMDocument=C.responseXML;else this.DOMDocument=null;if (this.DOMDocument==null||this.DOMDocument.firstChild==null){this.Error=true;if (window.confirm('Error loading "'+A+'"\r\nDo you want to see more info?')) alert('URL requested: "'+A+'"\r\nServer response:\r\nStatus: '+C.status+'\r\nResponse text:\r\n'+C.responseText);}},SelectNodes:function(A,B){if (this.Error) return [];var C=[];var D=this.DOMDocument.evaluate(A,B?B:this.DOMDocument,this.DOMDocument.createNSResolver(this.DOMDocument.documentElement),XPathResult.ORDERED_NODE_ITERATOR_TYPE,null);if (D){var E=D.iterateNext();while(E){C[C.length]=E;E=D.iterateNext();}};return C;},SelectSingleNode:function(A,B){if (this.Error) return null;var C=this.DOMDocument.evaluate(A,B?B:this.DOMDocument,this.DOMDocument.createNSResolver(this.DOMDocument.documentElement),9,null);if (C&&C.singleNodeValue) return C.singleNodeValue;else return null;}};
