As of Firefox v63, under Preferences > Privacy & Security > Forms & Passwords there is a button called "Saved Addresses..." which contains any name and address information that was previously entered into a form.
With this in mind, my question is if there is a way to prevent Firefox from automatically adding into Saved Addresses the names / addresses entered into a form from one or many websites while still saving addresses working on all other websites?
Also, I am aware there is a way to remove addresses from the Saved Addresses, what I am looking for is a way to prevent them from being added in the first place from one website.
