This is obviously a bug in the newest beta release and should be
reported there.Why the OP chose not to do this is a matter for speculation.

You are about to log into the site "google" with the username
"www%2Ecnn () 2Ecom%c0%AF%C0%AF%C0%C0%80", but the website does not require
authentication. this may be an attempt to trick you
Is "google" the site you want to visit.?
is this a 2.0.0.12 issue?

Firefox seems to have trouble with defining the proper hostname when

the hostname behind the at-sign is legit and the same as the URI that
requested an ssl connection, and this without a warning.

You can add as much garbage between .com and the @ sign.
So what else can we do?
PoC:
www.cnn.com%C0%AF%C0%AF%C0%C0%80 () google
www.gmail.com%C0%AF%C0%AF%C0%C0%80 () hotmail
ah heck we don't need that at all:
www.gmail.comxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx () hotmail
works fine also :)
