See attached html. This is an ordinary form, everything works fine.
I am the developer, I use Firefox. When I test, Firefox remembers all the fields (from prior tests) except the phone number field. If I double click there it lists an odd assortment of choices, none of which are phone numbers.
When I click submit, it asks me if I want it to remember the password for the phone number.
Why does it do that? Seems I must have something set up in an odd way.
