					"<tabbox flex='1' >" +
						"<tabs>" +

							"<tab id='recent-tab' label='Open Recent' linkedpanel='recent-panel'/>	" +
						"</tabs>" +
						"<tabpanels flex='1' >" +
							"<tabpanel />" +
							"<tabpanel />" +
						"</tabpanels>" +
					"</tabbox>" +
				"</box>";
	var box =  parseXUL(xulData);
	try{	
		document.documentElement.appendChild(box);
	}catch(e){alert(e)}	

when i execute this, it throws exception as "this.firstChild.setAttribute is not a function"

The following is "parseXul" function

function parseXUL (xulData){
	var parser=new DOMParser();
	var xmlobject=parser.parseFromString(xulData,"text/xml");

	if (xmlobject.documentElement.tagName == "parsererror")
	alert("Parsing Error");
	else return xmlobject.documentElement.cloneNode(true);
}

I don't get that exception when executing this code in JS shell in the context of browser.xul on firefox. If you have a problem you need help with and not a bug report, please ask in the newsgroups instead of filing a bug.
