"In the next few days, we will start the Nightly experiment which provides easy access to AI services from the sidebar.

If you want to try the experiment, activate it via Nightly Settings > Nightly Experiments (please see full instructions here).

Mozilla Firefox finally allows you to further protect local access to stored credentials in the browser's password manager using your device's login, including a password, fingerprint, pin, or other biometrics
