Okay, this sucks. The Javascript documentation
here says:
Examples
The following example would make the referenced window "chromeless" (chromeless windows lack toolbars, scrollbars, status areas, and so on, much like a dialog box) by hiding most of the user interface toolbars:
self.menubar.visible=false;
self.toolbar.visible=false;
self.locationbar.visible=false;
self.personalbar.visible=false;
self.scrollbars.visible=false;
self.statusbar.visible=false;
Yet when I run that it says "self.menubar is null or not an object".
Saying
self.menubar=false; runs without error, but does nothing to change the window chrome.
I HATE JAVASCRIPT!!!!
