I have an extension which uses XBL element inside an overlayed toolbar. Inside the overlay there is a label 'test' which should have displayed (at least it displays in Firefox 3.0.11). The element containing the XBL is there when i inspect with DOM Inspector but the XBL content is missing.

Reproducible: Always

Steps to Reproduce:
1. Install the example extension i attach
Actual Results:  
Nothing displays in the toolbar

Expected Results:  
It should display a label with text 'test'

Confirmed on Windows Vista. I don't see errors.
Regression range is http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5c289d7b5f17&tochange=55f801c97764
which seems to be bug 425153.
Can't look into this bug nor make it blocking.

The extension is using xpcnativewrappers=no (why?  I have no idea; that's not exactly a safe thing to do).  The fix for bug 425153 makes it so that a document that uses xpcnativewrappers (e.g. the browser window) cannot have a binding that wouldn't use xpcnativewrappers applied to its nodes.  So the behavior is as expected.

You probably want to take out the "xpcnativewrappers=no" line in your manifest...

The Firefox 3.5 "updating extensions" article has a blurb on this now. Couldn't find anywhere else that really stood out as needing to mention it, so if you find a place for it, please do say something about it.
