How to delete saved addresses and credit cards in Firefox for improved security and privacy
I prioritze data security. Even though some security and privacy configurations end up meaning my experience isn't as efficient as possible, I will always go for security over simplicity -- and you should as well.
Every day there's a new hack waiting for you to look the other way, so it can steal your data. While something as innocuous as a saved physical address might seem harmless, if someone were to uncover that data, they could use those details against you.

Better safe than sorry always applies to technology. The good news is the Firefox web browser does take your privacy seriously. It offers a number of options to help make your experience as secure as possible in this maddening world.
One thing users should be aware of is Firefox will not longer automatically fill out your physical address or credit card information. For me, the added security and privacy is worth the extra typing. Even though the Google commercial makes it seem like you'll miss out on things like concert tickets (because you have to spend the extra time typing your information), I'd much rather miss out than risk my address or credit card data falling into the wrong hands.
