Developer's DescriptionBy Collin JacksonGenerate passwords for Web sites automatically.Automatically generates per-site passwords if you prefix your password with @@ or press F2 beforehand. Prevents JavaScript from reading your password as it is typed. The same password will be generated at each subdomain: a.example.com matches b.example.com, a.example.co.uk matches b.example.co.uk, but a.co.uk and b.co.uk are different.
