Hello, I did just make a clean reinstallation of Thunderbird and while going through the setting I have notices that at Passwords / Save Passwords / `Show Passwords` my Account Passwords can be access with less effort. My question now is, why is this even a feature? In my mind, this should be by default off. Or at least informed me at the first account setup that my passwords are visible in the Settings, and if I want to set up a Master Password as well. Is there an option to have the Button `Show Password` disable? Or if a Master Password have to be, then set it for only access `Show Password` but not for the login in to Thunderbird.
