No. Superfish is not required by either the Admin_Menu nor the core Toolbar modules.

I'm sure : i'm logg on with a true user(with administrator rights).

So according to you, i have to download the drupal module called Superfish?

I can try to place this module into the FTP folder. But after, how to
activate this module without be able to display administration menu ?
