You might want to look into the existing "need a way of showing some
chrome UI over content" bug... I believe the short of it is that it
can sort of be done if the chrome stuff is opaque. If it's not, it
just won't work correctly no matter what you do with it, as things stand.
So how about as-things-change-in-1.9.2? Or is there another way to
accomplish our goal of showing visual indicators of layout boxes in
content without inserting new content (and hence disturbing the content
we are trying to debug)?
It seems like support for chrome-over-content would be a generic feature
of potential interest to many extension developers.
The autoscroll popup is probably the best way to do something like this
right now. Basically it's a transparent/translucent XUL panel.
