copied!<p>In my experience developing with Firefox, I've found in some cases the initialization code for various elements acts as if it were asynchronous. In other words, when you're done executing</p> <pre><code>var newBrowser = window.document.createElement('browser'); newBrowser.setAttribute('flex', '1'); newBrowser.setAttribute('type', 'content'); cacheFrame.insertBefore(newBrowser, null); </code></pre> <p>, your <code>browser</code> may not actually be ready yet. When you add the delay, things have time to initialize, so they work fine. Additionally, when you do things like dynamically creating <code>browser</code> elements, you're likely doing something that very few have tried before. In other words, this sounds like a bug in Firefox, and probably one that will not get much attention.</p> <p>You say you're using <code>onLocationChange</code> so that you can know when to add a <code>load</code> listener. I'm going to guess that you're adding the <code>load</code> listener to the <code>contentDocument</code> since you mentioned it. What you can do instead is add the <code>load</code> listener to the <code>browser</code> itself, much like you would with an <code>iframe</code>. If I replace</p> <pre><code>newBrowser.addProgressListener(listener); </code></pre> <p>with</p> <pre><code>newBrowser.addEventListener("load", function(e) { console.log('got here! ' + e.target.contentDocument.location.href); }, false); </code></pre> <p>then I receive notifications for each <code>browser</code>.</p>
