alice.it Script (may 2013)

hello, I use X-notifier (ex WebMail Notifier) with Mozilla Firefox, for many years. A few days ago I can no longer access "alice.it."
I downloaded the latest version of X-notifier (v3.3.3) but it did not work with the old script for alice (Jan 2012).
Then I also downloaded the latest script for "alice.it" (posted here in May, 2013) that you have modified to make it work with Forefox and Chrome. But it still does not work on Firefox.
If I try to connect with Alice, the first page that appears on the screen is this:
http://www.telecomitalia.it/?ref=1
and then you see this:
http://mail.alice.it/
to insert nickname and password
But, this way I just do a manual login to the account of alice.it
