How to Disable the “Save and Fill Addresses” Feature in Google Chrome

The Demographic Scraping Vector

Google Chrome defaults to a highly aggressive data retention architecture for web forms. By default, the browser runs a background “Autofill” engine that silently observes the text you enter into checkout pages, shipping forms, and registration portals. It actively harvests your full name, home address, phone number, and email address, storing this demographic data in a persistent local (and potentially cloud-synced) database. While designed for frictionless online shopping, it is a massive operational vulnerability. Anyone who gains physical access to your unlocked computer can easily view your complete home address in the browser settings. Furthermore, malicious web scripts can attempt to trick the autofill engine into populating hidden form fields. You must permanently paralyze this demographic caching engine.

How to Disable the Save and Fill Addresses Feature

You can permanently sever the browser’s ability to cache your personal information via Chrome’s Autofill settings.

1. Open the Google Chrome desktop browser.
2. Click the three vertical dots (⋮) in the top right corner and select Settings.
3. In the left-hand sidebar, click on Autofill and passwords.
4. Click on Addresses and more.
5. Locate the master toggle switch labeled Save and fill addresses.
6. Toggle this switch to the Off position (the blue background will disappear).
7. (Optional but recommended) Manually delete any existing saved addresses from the list below.

Total Form Isolation

The change takes effect instantly. Google Chrome will completely sever the software connection between its internal autofill database and the external DOM. The browser is now permanently barred from attempting to populate text boxes with your home address or phone number. When you encounter a shipping form, you are now strictly required to manually type your information. This guarantees absolute demographic privacy, ensuring that your core contact details are never cached in the browser’s memory or accidentally surrendered to a malicious web form.
