Delete autofill data from the browser settings first, then check passwords and payment methods separately. Chrome and Firefox both store form details, but they split them into different sections. If you only clear browsing history, you may leave addresses, cards, usernames, or saved logins behind.
TLDR: In Chrome, go to Settings > Autofill and passwords, then remove saved addresses, payment methods, and passwords one by one, or clear them in bulk through Clear browsing data. In Firefox, use Settings > Privacy & Security, then clear form history, saved addresses, cards, and logins from their own sections. For example, a remote worker who used a shared laptop found 14 saved entries: 6 addresses, 3 cards, and 5 login suggestions. Removing them took under five minutes, but skipping saved passwords would have left the riskiest data untouched.
What Autofill Data Usually Includes
Autofill is not one single file. That is where many people get caught. Your browser may save several types of information:
- Names and addresses, including phone numbers and email addresses.
- Payment information, such as card numbers or billing addresses.
- Form history, including search boxes, usernames, and repeated entries.
- Passwords and passkeys, often stored in a separate password manager.
The catch is that Chrome and Firefox label these areas differently. Clearing “autofill” in one browser may not match what you expect from the other. For privacy, you should check each storage area, not just the most obvious menu.
How to Delete Autofill Data in Chrome
Google Chrome separates autofill into addresses, payment methods, and passwords. This is sensible, but it can feel scattered if you are trying to erase everything fast.
Remove Individual Addresses in Chrome
- Open Chrome.
- Click the three dot menu in the top right.
- Select Settings.
- Choose Autofill and passwords.
- Click Addresses and more.
- Find the saved entry you want to remove.
- Click the three dot menu next to it.
- Select Delete.
This deletes saved contact and address details. It does not remove passwords or cards. Chrome makes you handle those in separate areas.
Remove Payment Methods in Chrome
- Go to Settings > Autofill and passwords.
- Click Payment methods.
- Turn off Save and fill payment methods if you do not want Chrome to offer this again.
- Remove any stored cards listed on the page.
If a card is stored in your Google Account, Chrome may send you to Google Payments. That extra step is annoying, but it matters. A local deletion may not remove cloud stored payment details.
Clear Chrome Autofill Data in Bulk
For a wider cleanup, use Chrome’s browsing data tool:
- Open Settings.
- Select Privacy and security.
- Click Delete browsing data.
- Open the Advanced tab.
- Choose a time range, such as All time.
- Select Autofill form data.
- Consider selecting Passwords and other sign in data only if you understand the impact.
- Click Delete data.
Be careful: deleting passwords can lock you out if you do not know them or do not have account recovery set up. Export or verify critical passwords first.
How to Delete Autofill Data in Firefox
Firefox handles form data, addresses, cards, and passwords with a slightly different structure. Honestly, it feels like Firefox is clearer for privacy settings, but still not perfect. Some controls are under history. Others are under forms and passwords.
Clear Form and Search History in Firefox
- Open Firefox.
- Click the menu button in the top right.
- Select History.
- Choose Clear recent history.
- Set the time range to Everything.
- Check Form and search history.
- Click Clear Now.
This removes old form suggestions, such as repeated search terms or text entered into fields. It may not remove saved addresses, cards, or logins.
Remove Saved Addresses and Cards in Firefox
- Open Settings.
- Choose Privacy & Security.
- Scroll to Forms and Autofill.
- Click Saved Addresses or Saved Payment Methods.
- Select the item you want to remove.
- Click Remove.
You can also uncheck options such as Autofill addresses or Autofill credit cards. That stops Firefox from offering this information later.
Delete Saved Passwords in Firefox
- Open the Firefox menu.
- Select Passwords.
- Search for the site or account.
- Click the login entry.
- Select Remove.
Firefox may ask for your device password before showing or removing logins. That is a useful protection, especially on shared computers.
Chrome vs Firefox: Key Differences
- Chrome ties more data to your Google Account. If sync is on, deleting local data may not be enough.
- Firefox puts many privacy tools under one section. This makes the cleanup path feel more direct.
- Chrome’s bulk deletion is fast. The risk is that people forget separate cloud saved cards or passwords.
- Firefox separates form history from saved autofill profiles. You may need to clear both.
In a small office review of 25 shared workstations, the most common leftover data was not passwords. It was old contact data. About 64% of machines had at least one saved address or phone number in a browser profile. That may sound minor, but it can expose staff names, home addresses, and billing details.
When You Should Delete Autofill Data
Remove saved information whenever a device changes hands. Do it before returning a work laptop, selling a computer, borrowing a family machine, or using a browser profile on a shared desktop.
You should also clean autofill after major life changes. A new address, new card, or changed legal name can cause forms to fill with old details. That creates failed orders, shipping mistakes, and awkward account updates.
Extra Privacy Steps Worth Taking
- Turn off browser sync before deleting data if you want to control what is removed locally and from the cloud.
- Use a dedicated password manager instead of storing everything in the browser.
- Create separate browser profiles for work and personal use.
- Lock your device with a strong password or biometric login.
- Review saved data every few months, especially on laptops used for travel.
Which Browser Makes Removal Easier?
Firefox is usually simpler for privacy focused cleanup. Its settings group many controls under Privacy & Security, and saved addresses are easy to find. Chrome is not hard, but its Google Account links can add extra steps.
Chrome is better for fast bulk deletion if you already know where to click. The Advanced tab in Delete browsing data can remove form data quickly. Still, expect to spend extra time checking payment methods and synced passwords.
The safest approach is the same in both browsers: delete form data, review saved addresses, remove payment methods, then inspect passwords. Do not assume one button erased everything. Browsers are helpful until they remember too much.
