If you’re a Firefox user, you can view your saved credit card numbers in the browser. This is a great way to keep track of your spending and make sure you’re always getting the best deals on credit cards. To view your saved credit card numbers in Firefox, open Firefox and click on the three lines in the top left corner of the browser window. This will show you all of your saved credit card numbers. You can select one of these numbers to see its details, such as its expiration date and interest rate. If you want to change or delete any of your saved credit card numbers, just click on the Edit button next to each number and then select either Delete or Change.


If you need your credit card number but don’t have your card nearby, it’s possible to retrieve it from Mozilla Firefox if the browser has stored it for you with Autofill in the past. Here’s how.

First, open Firefox on Mac, Linux, or Windows. In any window, click the menu button (three lines) in the upper-right corner, then select “Preferences” (on Mac) or “Options” (on Windows and Linux).

When the “Preferences” or “Options” tab appears, click “Privacy & Security” in the sidebar menu.

Next, scroll down to the “Forms and Autofill” section and click the “Saved Credit Cards” button.

In the window that pops up, Firefox will show a list of all credit cards it has saved. Select the card you’d like to see the number for and click “Edit.”

In the “Edit Credit Card” window, you’ll see the full credit card number in the “Card Number” box. If the expiration date and the name on the card have been saved, those will be listed, too.

Note that Firefox will never save the three- or four-digit card security code (often called a “CVV number” or “CSV number”) found on the front or back of your credit card. To get that, you’ll need the actual card itself.

If you’d like to remove a credit card from Firefox, hit “Cancel” to go back to the main card list, then select a card and click “Delete.” Firefox will instantly forget the saved card information. Good luck!
