Mozilla is preparing a very useful change in Firefox Lockwise, the password manager built into Browser. Firefox's internal page will display an authorization window that will ask for your Windows 10 credentials before allowing you to edit or view saved connections.
This change is really important and welcome, because if you accidentally forget to lock your computer, anyone can open Firefox Lockwise and steal saved codes access. An extra level of protection is very important in this case.
The new feature is already available with the release Firefox Nightly 76.0a1 and prompts the user trying to access Firefox Lockwise to enter Windows 10 login credentials, e.g. a PIN, before viewing, copying, or editing stored login credentials.
If someone user does not know the password, PIN or other control identity, Firefox will not allow it to see the credentials.
This method makes Firefox Lockwise more secure, but the application it has a usability issue. The prompt to enter Windows credentials pops up every time you want to see the credentials for each of the saved accounts, and it's really annoying.
It could of course be resolved in the future.
