Firefox incorrectly formats 7 digit phone numbers for no reason by adding a "+1" and stripping out the "-"s (dashes). It is not up to Firefox to arbitrarily decide how I want phone numbers entered. This can be seen when you go to "Privacy & Security", "Forms and Autofill", and "Saved Addresses". Edit any of your saved addresses or add one if you don't have any addresses saved. Enter a phone number "456-789-1234", save the entry, and open that entry again. The phone number will now be "+14567891234". If Firefox wants to make the reformatting an option, I'm OK with that so that I can turn the intrusion off. version 109.0
