UPDATE:
done what suggested by dev.:
"Save the following in Options and then reload the repubblica.it page for the settings to take effect:

List of hostnames (one per line):
repubblica.it"

result: REFRESH and again and again...i really think this is a fake add on

List of hostnames (one per line).
repubblica.it

List of hostnames (one per line).
