Firefox-Passwords-Decryptor: Extracts and decrypts passwords saved in Firefox

I would love to hear any suggestions for how to remove all my stored passwords in Firefox. I used to use Firefox password manager but moved to Bitwarden. It has been surprisingly difficult to remove passwords completely as I'm using Firefox Sync, and they just get restored from one of my devices.

You have to sign out of all devices and choose to delete the local data while you do so.

Another option is to delete your Mozilla account and recreate it, if you're not using it for anything other than Firefox Sync.
