Extends Firefox's built-in password manager Puntuado con 5 de 5 estrellas
There are sites where Firefox is unable to stick your logons, with QuickPasswords it will stick them there as well.
There are sites where Firefox is unable to remember your logons, with other great extension 'Saved Password Editor' it will remember there as well.
Both add-ons are very nicely thought and done, they are complementary.
EDITed : 'Password Editor' was, is of course 'Saved Password Editor'
