User Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Build ID: 20120208060813 Steps to reproduce: 1. I typed chrome://browser/content/browser.xul into the adress bar of the Firefox browser (let's call it the layer 1 FF). 2. So I get a second browser with its own adress bar (which we'll call layer 2 FF). 3. In layer 2 FF click on the + sign to open a new tab. 4. Switch back to the first tab of the layer 2 FF. 5. Type any web adress (for example www.google.de) into the adress bar of the layer 2 FF and press return key Actual results: Nothing happens, but when you either - switch to the second tab of the layer 2 FF and back to the first one - minimize the browser windows and maximize it back the Google page can be seen. Expected results: The Google website (or whatever website you typed in) should be shown directly. Generally the nesting of chrome://browser/content/browser.xul browsers inside each other (especially in combination with opening tabs of browsers inside browsers inside browsers) is rather glitchy. Play around with it (some kind of Firefox inception) and see yourself.
Thanks for your report! You're right, browser.xul was not designed to be used like that, but there's no reason for us to forbid it from being loaded in a tab, especially since the ability to load other chrome:// URLs in a tab is useful for development. (See also bug 626993).
