Norton Identity Safe Vault is not accessible in Firefox 40.0.3 when first starting Windows 10. The toolbar says "Access Vault", and it gives a caution message "System Restart Needed". When restarting Windows 10 you get the normal "Vault is Closed" on the toolbar, then allows password access. The password window is not in the foreground as in the past. I upgraded to Windows 10 from Win7.
