OK Patrick,

my is not really a problem...I can run frefox both both from command line both using Gnome.

Other time yet I understood "by chance", after some time, how to do better something that was not  what I really would like it

thank you

Angelo

Not necessarily. A script can do more than a link because it can set up
environment variables before calling the target program.

Why do you need to call firefox using sudo? I presume the errors are
caused by sudo's environment not being what Firefox needs. However I
still don't understand what your problem actually is so maybe I should
just shut up. As I said before I don't use Gnome, so creating a desktop
shortcut for that environment is outside my comfort zone. All I meant
to say is that if your target binary is for some reason in the wrong
place, you can get round it using a script. That's all.
