Want Safer Browsing? Should You Turn Off Firefox’s Credit Card Autofill Feature?

Mozilla Firefox offers a convenient credit card autofill feature, allowing users to save and automatically enter credit card details—such as card number, name, and expiration date—on web forms. This can streamline online shopping and payment processes, but users may wish to control this feature for privacy or security reasons.

Key Points

  • Credit card autofill is being gradually introduced in select countries: Austria, Belgium, Canada, France, Germany, Italy, Poland, Spain, UK, and US.
  • The feature stores your payment information securely, but you can require device sign-in for added protection.
  • Users outside supported countries can manually enable or disable this feature using Firefox’s advanced settings.

How to Check and Adjust Credit Card Autofill in Firefox:

  1. Open Firefox and go to the Settings page.
  2. Navigate to the Privacy & Security section.
  3. Scroll down to the Autofill area to manage payment methods.
  4. Enable or disable credit card autofill by toggling the “Save and fill payment methods” checkbox.
  5. For additional security, enable “Require device sign in to fill and manage payment methods.”

Advanced Method: Force Enable or Disable Credit Card Autofill

If the feature isn’t available in your country or you want to remove it, follow these steps:

  1. Type about:config in the Firefox address bar and press Enter.
  2. Accept the warning to access advanced settings.
  3. Search for the preference: extensions.formautofill.creditCards.supportedCountries
  4. To enable autofill in your country, add your country code (e.g., IN for India) to the comma-separated list.
  5. To disable, remove your country code from the list.
  6. Changes take effect immediately.

Benefits

  • Enhanced convenience for online transactions.
  • Flexible control over personal data and privacy.
  • Ability to customize settings regardless of location.

Considerations

  • Only enable autofill on trusted devices.
  • Use the sign-in requirement for extra security if saving payment methods.
  • Regularly review and update saved payment information.

This approach gives you full control over Firefox’s credit card autofill, letting you balance convenience and security as needed.
