A while back there have been some requests from developers (seconded

They'd like to use this to avoid having to create their own UI. In
Firefox this could manifest itself by the spinner that replaces the
favicon when loading a tab.
Is there a reason we shouldn't expose a hook for this?
Sounds reasonable. Currently at least in Gecko one can emulate this with some
dummy iframe and call
iframe.contentDocument.open(); to start the spinner, and
iframe.contentDocument.close(); to stop it
(assuming of course no other loading is keeping the spinner running).
