Steps

Goal: Enable autofill, ensure the data is saved, and rule out form attributes and extensions.

  • Check if autofill is enabled in your browser settings.
  • Good: It is enabled. Proceed to Check saved data.
  • Bad: It is disabled—enable it and reload.

Enable autofill

Goal: Turn on autofill for addresses, passwords, and payment.

  • Chrome: Settings → Autofill → Addresses and more, Passwords, Payment methods—each on.
  • Firefox: Settings → Privacy & Security → Forms and Autofill → Addresses and Passwords on.
  • Edge: Settings → Profiles → Personal info, Passwords, Payment info—each on.
  • Safari: Preferences → Autofill → enable each category.
  • Good: Autofill is on. Proceed to Check saved data.
  • Bad: Still off—enable and reload.

Check saved data

Goal: Ensure the browser or password manager has the data.

  • Chrome: Settings → Autofill → Addresses. Passwords: chrome://password-manager.
  • Firefox: Settings → Privacy → Logins and Passwords.
  • Add the address or password if it was never saved. Fill the form, choose “Save” when prompted.
  • Good: Data is saved. Proceed to Check the form.
  • Bad: No data—add it and retry on the next visit.

Check the form

Goal: See if the site blocks autofill with autocomplete attributes.

  • Right-click the form field → Inspect. Look for autocomplete="off" or missing autocomplete.
  • If the form uses autocomplete="off" or non-standard names, the site blocks autofill. The site owner must fix it. You can use a password manager extension to fill manually.
  • Good: Form allows autofill. Proceed to Disable extensions.
  • Bad: Form blocks it—use the password manager extension or contact the site.

Disable extensions

Goal: Find which extension blocks autofill.

  • Open the form in incognito. If autofill works there, an extension blocks it in normal mode.
  • Chrome: chrome://extensions. Firefox: about:addons. Disable extensions one by one. Test the form.
  • When autofill works, that extension was blocking it. Whitelist the site or disable the extension for it.
  • Good: You found the extension. Whitelist or disable for the site.
  • Bad: All disabled and still fails—try another browser or device; check sync.

When to get help

  • Autofill is enabled, data is saved, the form allows it, and no extension blocks it—but autofill still does not work. The site may have a bug. Contact site support. If you own the site, add correct autocomplete attributes.

Verification

  • Autofill suggestions appear when you focus a form field.
  • Address or password fills when you select it.
  • If an extension was the cause, it is whitelisted or disabled for the site.

Is the data saved in the manager?

Add the data and retry

Fill the form manually. When the browser prompts "Save password" or "Save address," choose Save. Next visit, autofill should work.

Does the form use autocomplete="off"?

Some sites block autofill with autocomplete="off."

Does autofill work in incognito?

Incognito disables most extensions.

Open incognito. Load the form. Good: works in incognito—extension blocks autofill. Disable extensions one by one. Bad: still fails—try password manager extension or another browser.

Frequently asked questions

Why would autofill not work?
Autofill can be disabled in browser settings, the form may use non-standard attributes browsers do not recognize, an extension may block it, or the data may not be saved in the password manager.
What form attributes does autofill need?
Browsers use standard HTML attributes: autocomplete="street-address", "email", "username", "current-password", etc. If the site uses custom or wrong attributes, autofill may not trigger. The site owner must fix this.
Does a password manager replace browser autofill?
Password managers (1Password, LastPass, Bitwarden) have their own autofill. Enable the extension and ensure it has permission to run on the site. If both browser and extension are on, they can conflict—use one.
