Most major web browsers include built-in features to automatically fill personal information, with several introducing advanced AI-powered enhancements this year.

Before setting up your browser autofill

Move the mouse over toward the right hand side of the page, click on the double arrow, and hold it down. Drag the arrow the to the right hand side of the screen and release. Similarly click and drag the left-hand side of the window to the middle of the screen. That should keep this window from getting covered up as you proceed.

Firefox (Windows/Mac)

Firefox lets you have multiple profiles.

  1. Firefox → Settings .
  2. Click on Privacy & Security (Left hand taskbar)
  3. Scroll down under Browser Privacy on the right
  4. To Addresses and more
  5. Click the save and autofill address check box
  6. Click “manage addresses and more” arrow and fill out the form that comes up when you click the add button.

Chrome (Windows/Mac)

  1. Chrome → Settings
  2. Autofill and passwords → Addresses and more
  3. Turn on Save and fill addresses and (optionally) add an address.
  4. Then, on your site, when they type an address the first time, Chrome may prompt to save it. 

Microsoft Edge (Windows/Mac)

  1. Edge → Settings
  2. Profiles → Personal info (addresses) and Payment info (depending on version)
  3. Turn on the toggles to save and fill form info.

Microsoft documents that Edge can store/import “Addresses and more (autofill data)” under profile/import features. 

Safari (iPhone/iPad)

  1. Settings app → Safari → AutoFill
  2. Turn on Use Contact Info
  3. Make sure your personal Contact card (“My Info”) is set and has your address, email, etc.
  4. Optionally enable credit cards if you want, but for voter info you mainly need Contact info. 

Safari (Mac)

  1. Safari → Settings (or Preferences) → AutoFill
  2. Enable Using information from my contacts and set/complete your “My Card” in Contacts.

(Apple’s Safari AutoFill is fundamentally driven by your saved contact card + AutoFill settings.) 


Tip (all browsers)


If you don’t have tabs visible (or it won’t “tear off”), first make sure you’re not in a special full-screen/tab-group mode hiding the tab bar. Then try again by dragging the tab slightly downward before moving it away.

Background information

Leading Browsers with Autofill

  • Google Chrome: Chrome remains a leader in autofill technology. As of late 2025, it has expanded its “Enhanced Autofill” feature to support sensitive identification documents, including passports, driver’s licenses, and vehicle registration info. It also supports standard information like addresses, payment methods, and passwords.
  • Microsoft Edge: Edge serves as the central hub for Microsoft’s autofill ecosystem. Following the discontinuation of Microsoft Authenticator’s standalone autofill in August 2025, users are encouraged to sync their personal data directly through Edge. It can automatically complete names, email addresses, phone numbers, and delivery information.
  • Apple Safari: Safari continues to use iCloud Keychain to autofill contact information, credit cards, and passwords across all Apple devices. It can pull data directly from your “My Card” in the Contacts app.
  • Mozilla Firefox: Firefox offers standard autofill for addresses and credit cards. Users can manage these in the “Forms and Autofill” section of the browser’s privacy settings. 

What Information Can Be Autofilled?

Modern browsers in 2025 can typically handle the following data:

  • Contact Details: Name, email, phone number, and physical addresses.
  • Payment Information: Credit/debit card numbers and expiration dates (often requiring a CVV for security).
  • Official IDs (New in 2025): Specifically in Chrome, you can now store and fill passport and driver’s license numbers.
  • Login Credentials: Usernames, passwords, and passkeys. 

How to Enable or Manage Autofill

  • Chrome: Navigate to Settings > Autofill and passwords.
  • Edge: Go to Settings > Profiles > Personal info or Payment methods.
  • Safari: Go to Settings (or Preferences) > AutoFill.
  • Firefox: Navigate to Firefox >Settings > Privacy & Security > Addresses and more

For enhanced security and cross-browser functionality, many users in 2025 also utilize dedicated extensions like Bitwarden, 1Password, or Dashlane, which offer more robust encryption and organization than standard browser tools.
