Firefox started supporting user/password export into CSV file
-
Just FYI, Firefox started supporting user/password export into CSV file from version 79 (currently in Nightly build): https://support.mozilla.org/ja/kb/export-login-data-firefox-lockwise
So, you now can export your password without any third-party tools but just by installing Firefox Nightly and starting it as using the existing profile or syncing passwords via Firefox Sync.
I actually could import Firefox passwords by using this way + PasswordImport feature.
