Auto fill is now storing my security number as well as my credit card number. How can I stop this? Thanks

I've been concerned for sometime about the amount of information that autofills on forms but failed to find security settings to prevent this. Today I find that not only my credit card number but also my credit card security number was there for autofill on a website that I was using for a purchase. I don't think I have ever used that site before but I believe it to be safe.

If you do not want Firefox to remember form history you can turn it off. You can also clear individual entries, or the entire form history. For details of how to do that see the Control whether Firefox automatically fills in forms article.

If you want to clean your browser's previous remembered private data. You can just follow these steps:

  1. Click "Tools" in the menu bar
  2. Choose "Options".
  3. Turn to the "Security" tab
  4. You can cancel the tick in front of "Remember website passwords".
  5. Then click the "Saved websit passwords" button, and then click the "Remove all" button.

May this answer help you.

Note that disabling Tools > Options > Privacy > History: "Remember search and form history" will not remove already stored saved form data. You will have to remove all saved form data manually via Delete browsing, search and download history on Firefox or remove individual entries.
