Chrome Autofill Address — Complete Guide

In this tutorial, you'll learn about Chrome Autofill Address. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

Hook

You fill in a shipping address form on a shopping site. Chrome used to autofill it, but now it does not suggest anything. Or you save a new address in Chrome Settings, but it never appears in autofill suggestions.

The Wrong Way

Disabling "Addresses and more" in Chrome settings and re-enabling it does not fix missing address suggestions if the autofill profile database is corrupted.

# BAD: Toggling address autofill
# chrome://settings/addresses → Disable → Re-enable

Address autofill toggled off and on
Still no suggestions — same result

Toggling does not repair the underlying data.

The Right Way

Check address settings, clear the autofill profile, and verify form detection.

# 1. Check address autofill is enabled
# chrome://settings/addresses → "Save and fill addresses" → Enable

# 2. Check saved addresses
# chrome://settings/addresses → View saved addresses
# Are your addresses there? If not, add them.

# 3. If addresses are saved but not suggesting:
# The website's form may use non-standard HTML names
# Chrome detects forms by input name attributes: "address-line1", "postal-code", etc.

# 4. Clear the autofill profile database
# Close Chrome
killall chrome

# 5. Rename the autofill database (Chrome rebuilds it)
cd ~/.config/google-chrome/Default
mv Web\ Data Web\ Data.bak

# 6. Start Chrome and re-enter addresses
google-chrome

New Web Data database created
Enter address on a site — Chrome prompts to save ✓
Autofill suggests saved addresses on forms ✓

If rebuilding the database does not work, check chrome://flags:

# chrome://flags → Search for "autofill"
# #enable-autofill-address-profile-save-prompt — Enabled
# #show-autofill-type-predictions — Enabled

Prevention

• Use standard shipping forms (Amazon, eBay, major retailers) — they use proper HTML attributes.
• Keep Chrome updated — autofill detection improves with each version.
• Regularly review and update saved addresses in chrome://settings/addresses.
• Use Chrome sync to back up autofill data to your Google account.
• Avoid using incognito mode for shopping (autofill is disabled in incognito).

Common Mistakes with autofill address

1. Non-exhaustive pattern matches that compile with warnings then crash at runtime
2. Misunderstanding that String is [Char] with poor performance for large text operations
3. Using foldl instead of foldl' causing stack overflow on large lists

These mistakes appear frequently in real-world CHROME code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
