NoTabNab: Protection Against the "Tabnabbing Attack"

In recent years phishing attacks have become one of the most important problems of online security. Aza Raskin, the creative lead of Mozilla Firefox team, proposed a new type of phishing attack, "Tabnabbing attack" as he names it. The attack is different from classical phishing attacks; while classical attacks rely on deception of users with a similar URL and/or content in appearance to the original site, this attack uses the authors' memory weakness and false perception that browser tabs are immutable i.e., do not change while inactive. They develop a Firefox add-on to protect users against this attack.
