Lock private browsing behind Face ID.

[jotaro-gogogo]

Apple recently announced that Safari incognito mode could be locked behind Face ID, this idea would be very helpful and welcomed if implemented on Firefox.

Add an option that if the user enables it, all private browsing/windows will get locked each time the user changes to normal/not-private browsing and could only be unlocked if the user willingly wants to unlock them, don’t launch Face ID automatically.

It's a great idea but I hope its optional and not mandatory. Also please include both fingerprint and face recognition if Mozilla is going to include this feature.
