but now show 2 files key4 and key3... and other other logins.json.tmp

key3.db [v58+] key4.db and logins.json These are the Password files.

See if renaming logins.json.tmp to logins.json restores the passwords.


In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.

How can i restore those files?! I did this: If i erase or remove the key4.db and let the files logins.json and key3.db remain the passwords that i already put in this new Firefox version will they disappear and still does not show the other (old) passwords.

If you replace logins.json with an older copy as you need to do if you want to restore old passwords then you will lose passwords you added to the current logins.json. You will have to revisit currently saved websites to save the passwords once again to add them to the old database.

The logins.json and key3.db files need to match to have the correct encryption key.
