Firefox should recognize the credit card number automatically and not store is as part of saved form data.


To remove saved form data:

  • Click the (empty) input field on the web page to open the drop down list
  • Highlight an entry in the drop down list
  • Press the Delete key (on Mac: Shift+Delete) to remove it.
