[Greasemonkey] How to ad an icon to the Status bar?

[Stefano POGLIANI]

Is it possible (and, if it is, how) from a GM script to add an icon to 
the FF Status bar?
I would like to give my users the possibility to actually use this
mechanism as a type of "minimized window".... so that, when they will
hit the icon, my GM script will execute some further processing...

Thanks a lot in advance for your help
Best regards

P.S.	I would prefer to keep it in a script instead of creating an 
extension...
