Using alwaysLowered from chrome extension does not seem to work

[rael]

I have thrown in the towel with using a signed script to open a window
with alwaysLowered.  It seems clear from the firefox source code, and
from a person on this group (Daniel), that this cannot work and that
this must be done from a  window that has a "chrome" parent.

Aside from the obvious gripe (why nobody from the mozilla organization
bothered to take 5 minutes to document this fact in the Javascript
documentation on the mozilla site), I am still not seeing any effect
from using the alwaysLowered feature.

I downloaded a "helloworld" extension example from MozillaZine (http://
kb.mozillazine.org/Getting_started_with_extension_development) and
added to it the opening of three windows, two of which have the
alwaysLowered feature set.  Essentially, this tutorial installs a new
menu item underneath the Tools menu titled "Hello World!".  When you
click on it, it opens a little window with a close button.  I replaced
the opening of this small window with an open of three windows, as
above.  Firefox opens the windows, but refuses to place them
underneath any others on the screen.  Again, I am running this under
Linux.

Here is the overlay.js, which I modified from the example:

var Helloworld = {
        onLoad: function() {
                this.initialized = true;
        },

        onMenuItemCommand: function() {
                var features = "top=0,left=1," +
 
"dependent=yes,menubar=no,location=no,resizable=no"

                var tv_features = features +
                        ",alwaysRaised=yes,width=500,height=200";

                var tv_win = window.open("", "tv", tv_features);

                var full_features = features +
                        ",alwaysLowered=yes,width=1000,height=400";

                var full_win = window.open("", "full", full_features);

                var full_winII = window.open("", "full_II",
full_features);
        }
};

window.addEventListener("load", function(e) { Helloworld.onLoad(e); },
false);

I tried coding the above with an added variety of calls to the
PrivilegeManager to no avail --- I do believe that an extension is
granted these by default anyway, but I'm trying anything to get this
to work.  I also put working URLs in each of the window.open calls
above, and they load just fine, but still no lowering of any sort
happens.  I also tried using the tv_win to open the other windows, but
that didn't work (no lowering) either.

So, what am I doing incorrectly?  Is this alwaysLowered feature
something that someone, somewhere on this planet has ever used
successfully?
