Status: UNCONFIRMED

(Firefox :: Tabbed Browser, defect)

Attachment: Test extension XPI

When I try open a xul page with <browser> element I see NS_ERROR_FAILURE in console. Also "pageshow" event isn't triggered for the <browser> for me. (unless it's normal and I don't know about it)

But when I open the xul page in own window (i.e. outside Firefox window) using window.openDialog("chrome://adress.xul") I don't see the error and "pageshow" is triggered.

I tried all possible values of "type" attribute: content, content-primary, content-targetable and chrome.

I created test extension with problematic xul page. Test xul page is at chrome://browserpageshoweventtest/content/test/test.xul. I don't see bug after window.openDialog("chrome://browserpageshoweventtest/content/test/test.xul"); in context of main Firefox window.

The error:
Error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIWebNavigation.sessionHistory]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://global/content/bindings/browser.xml ::  :: line 724"  data: no]
Source file: chrome://global/content/bindings/browser.xml

XUL (test.xul):
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?> 
<!DOCTYPE window>
<window id="test1"
        xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
        onload="onLoad();">
  <script type="application/javascript" src="test.js"/>
  <browser id="content" type="content-primary" src="about:blank" flex="1"/>
</window>

JS (test.js):
const Cc = Components.classes;
const Ci = Components.interfaces;
function onLoad() 
{
  console.log("window - onload")
  window.gBrowser = document.getElementById("content");
  gBrowser.addEventListener("pageshow", onBrowserPageShow, true);
  runTest();
}
function onBrowserPageShow()
{
  alert("xul:browser - onpageshow");
  console.log("xul:browser - onpageshow");
}
function expectedResult() 
{
    gBrowser.dispatchEvent(new Event("pageshow"));
}
function runTest() 
{
    gBrowser.loadURI("about:home");
}

I tested it with my FF Portable 23.0.1 and with Nightly 26.0a1 (2013-09-08) (on Nightly only type="content-primary")
