Mozilla developers without generating a new release through the experiment system
Collected telemetry showed an abnormally high level of authentication problems using system credentials when trying to access browser-stored passwords. In 20% of cases, users were unable to verify and were not given access to their saved passwords. There are two main reasons that are likely to be the source of the problems:
- The user may not remember or know their system password because they are using an auto-login session.
- Due to the lack of clear explanation in the dialog, the user does not understand that a system password is required and tries to enter the password for the account in the Firefox Account used to synchronize settings between devices.
It was assumed that system authentication would protect credentials from prying eyes if the computer was left unattended if the master password was not set in the browser. In fact, many users were unable to access their saved passwords. The developers have temporarily disabled the new feature and intend to review the implementation. In particular, they plan to add a clearer description about the need to enter system credentials and disable the dialog for automatic login configurations.
