I'm not sure where the password came from. I log in using a different password for my imdb account which is the only one that shows up in password manager. When I log in, firefox asks if I want to save/update password but it is the long password in the box and not the one I logged in with. I've tried saving, not saving, updating etc., nothing works. Does that make sense?

Some websites modify the password field when you submit the login form after they have copied the password to a hidden field to prevent browsers from storing the password. In such a case you can edit the password in Lockwise and create a login block exception to prevent updating this password.

The password doesn't appear in lockwise.

If Bitwarden complains about it then it must be present in logins.json and Firefox might skip this entry if it is corrupted.

You can temporarily set signon.debug = true and check the Browser Console for possible login related messages after you start Firefox and open about:logins (Lockwise).

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

Do not forget to reset signon.debug to false after you are done testing.
