It worked!!!! Tools - Options - Manage Add-ons allowed me to remove the Yahoo Toolbar. Thanks for the advice!!

Any idea how to have Firefox quit when I close it? The screen exits, but the application remains active after I close it. Since I get a message that Firefox is already running when I re-launch it for a future session, I am forced to Control/Alt/Delete to end the Firefox process before it can be re-initiated.
