i restored my windows by mistake last night and then realized i lost all my passes when i had to download ff again, then i searched on the old windows folder and found the needed key3.db and logins archives there, i tried to open key3.db and all my logins are there but they're encrypted. THe problem is i've already transfered them to the new profile folder but my passwords are still empty -already tried deleting the profile and creating a new one What else i can do?

Chosen solution

OH NVM! It didn't work because i still had FF open while transfering the files, now i tried again and it worked! Thank you so much Cor-el and Ed!

You need two files.

logins.json and that key3.db file.

Note that the encrypted names and passwords are stored in logins.json and that key3.db is storing the encryption key. You need a key3.db file that matches the logins.json file to be able to decrypt its content. Both logins.json and key3.db need to be placed in the Firefox profile folder while Firefox is closed.

You can use this button to go to the current Firefox profile folder:
