// Purpose : Script to test if visitors use an older version than Firefox 1.5 and display an invitation to upgrade. Linux users don't get this alert since it is their distro's job to update their repository 
// needs to be loaded with onload event on body -> modification of includes/model.php
// this script is intimately linked with our Cavendish style, it would have to be adapted if we were to change of layout
