This will explain how I changed the Joomla Icon in the browsers address bar and page tab. 1st this works on Joomla 1.5 as it appears most templates use the admin favicon.ico.  

There are 2 websites where you can create an icon on line.

http://tools.dynamicdrive.com/favicon/

http://www.degraeve.com/favicon

After creating your icon, rename the current favicon.ico to faviconico.old in the //administrator/templates/Khepri directory then upload your new favicon.ico in it's place. That worked for me.
