Since the release of Firefox 57 (Quantum), existing password export plugins are not working. In Firefox 57 and later versions (current version is 61), there is no way to export saved passwords to a file.
As you likely aware, Firefox saves all passwords in its profile folder. In fact, you can manually backup Firefox passwords by backing up two files located in your Firefox profile folder. You can refer to our how to backup Firefox passwords in 57, and later versions guide for directions to manually backup passwords.
If you don’t want to manually backup those files every time you update a password or save a new password, you can use the help of third-party programs to export passwords saved in Firefox 57 and later versions.
