Firefox password autocomplete

Firefox password autocomplete

i have a problem with Firefox autocomplete in login forms. When i enter a password and a username for the first time it asks me if i want to remember them, i click on "remember" and it saves the data, but when i log out and then return to the login page it shows me nothing. The password is autocompleted only after i enter the username. Is there a way to do the autocomplete immediately like in any other browser?
