How does one disable formhistory since it records valuable personal information?

When filling out a form to purchase something, the type ahead filled out the rest of my credit card number. I tracked it down to the formhistory.sqlite file. The number was in human readable form and labeled as a card number. The authorization code was also in the file. I also found the information in a formhistory.dat file but not quite as easy to read. Both files had permission to be read by everyone. I did not find a way to disable the formhistory feature. I have deleted the files, touched the files (UNIX command which creates a zero length file), and changed the permissions so that I can not write to the files. I do not know how FF will react to this.

hi m35_2,

I think you are referring to the form auto-complete feature. That article will show you how to disable the feature completely or how to modify individual entries.

Hopefully this helps!

That solved the problem. I also did some additional test with the check removed from the box. First, FF did not complain with an unwritable file (formhistory.sqlite). Second, without the file existing, FF created a file but it did not have any form data in it. I decided to go with the check removed and with an unwritable file. Computers are famous for items being restored and having problems return. Thanks for the help.
