Hello, I have a security suggestion for Firefox for Android. Android API allows apps to be aware that a new fingerprint was enrolled in the device, preventing potentially unauthorized access to apps (in case of a leaked PIN or device theft). https://developer.android.com/reference/android/security/keystore/KeyPermanentlyInvalidatedException For me, it will be a great security improvement if Firefox could be able to detect new fingerprints enrollment in my device and prevent access to my passwords, maybe asking for my Firefox account password one more time. Thanks!
