At times, I see Chrome / other browsers glitch and incorrectly autofill fields.

For example, a common one: A donor autofills their payment info, and the card expiration date is added to the donor-entered amount field on a donation form, causing the transaction to process for that amount, rather than their selected amount.

You can add autocomplete=off as an attribute to HTML elements -https://www.w3schools.com/tags/att_input_autocomplete.asp 

Could we have a checkbox that does this for data elements on donation forms?
