Now IÕm going to
show you an extension I built for Firefox to demo the capabilities of XUL,
the Extension System, and the Mozilla platform.
This system adds
a line of thumbnails under the tab strip that is brought up when you click on
the session history section of the back and forward buttons, showing you your
session history and providing you with a way of navigating forward and
backward quickly.
My extension
adds this UI using the overlay mechanism I was just talking about, uses the
canvas control to render the thumbnails, and various other DHTML tricks to
create the sliding interface.
