Feature request for a "super primary password"

[innovation]

Existing primary password for Firefox:       prevents from filling in and changing passwords, but you can just cancel the dialog box and use all websites including email etc. with PREFILLED passwords -> not so secure when people around you. When credit cards on shopping websites are registered, someone could make orders, for example...

Super primary password (super primary plus primary):  if activated and the browser started, you must fill in a "super primary" so that it unblocks the browser. You can only browse when you unblock the blocked browser after a fresh start. When the browser is closed, it again blocks the browser completely, but can be unblocked again by filling in the "super primary".

-> feature request for the "super primary password" (primary and super, complete block of browser that needs to be unblocked after restart)
