Dear ideato the 'Top 25 Contributor',

Thank you very much regarding your answer but it need any confirmation to saving password. example: I login in any site and fill email and password field. Its save my password but no need any confirmation to save (its autosave machine). After log out, the email and password field will still blank (user no see the email and hidden password like ******). How to setting it? Please help. Thank you so much.

Hello, did you try to set the above parameters in my first reply ?

Be sure you are NOT in Private Browsing .

can you see the passowords in Password Manager ?

If you can not see any passwords in Password Manager window (Show Passwords) then your passwords are probably lost, then delete the key3.db and delete or rename the signons.sqlite file and all signons#.txt files (e.g. signons3.txt and signons2.txt) in the Profile folder - Firefox and check it again.

thanks again

You will always have to confirm if you want Firefox to store a new name and password, you can't do that automatically as that would be a security risk. Imagine that such a feature would be enabled on a public computer.

Maybe look at another (external) password manager if the build-in Firefox Password Manager don't satisfy your needs.
