Copy your Firefox shortcut and add the url for the WeatherChannel.com after a space to the end of Target: in the properties on the shotcut tab, then on the General tab change the name of the shortcut. see row #3 of the table in *http://kb.mozillazine.org/Command_line_arguments ---- I would consider that to be very inefficient unless it is a mobile device What I would do instead is create a keyword shortcut and invoke it on the location bar by its keyword shortcut.
