Hi Harold, this article has the basics on the built-in Password Manager: [[Password Manager - Remember, delete and edit logins and passwords in Firefox]] If you do not want saved logins to Sync, you can deselect them on the Sync section of the Settings page: [[How do I choose what information to sync on Firefox?]] (I guess do that first before saving anything.) If others have access to your computer you can increase the encryption level Firefox applies to your saved logins on disk, and also require entering a password to view or copy them: [[Use a Primary Password to protect stored logins and passwords]] Important: don't forget it because resetting it erases all the saved logins.
