You have to have an object reference to the browser before you can do this. If you mean you want to do this to a live browser, than you can gain an object reference with the Shell object's Windows collection:

oShell = CREATEOBJECT("Shell.Application")
FOR EACH oWindow IN Shell.Windows
  IF oWindow.LocationURL = "http"
    * Window instance is IE, not Explorer
    oWindow.Navigate("www.myurl.com")
  ENDIF
ENDFOR
