I'm looking into developing a Firefox extension, and would like my 'toolbar' to run in the 'client' area, since it will appear and disappear based on the page that they are on. One example of a client bar that does something similar is the Invisible Hand toolbar. Most of the extension tutorials show how to build a 'regular' toolbar.
I'm looking for a) the right name to call this kind of client widget, and b) links to tutorials on this kind of extension. I just need to be pointed in the right place. Thanks!
