Trying to Import a csv address book file to Thunderbird address book. Unable to get 'Match field names' to work. Unable to set/change any Address book field names. Each field name seems to be fixed / frozen to the default name of the expected column/ field name. There is a drop down list for each field, but only one option exists in the drop down list. So, I can not get my csv to translate/convert over to the Thunderbird fields. Same problem seems to exist in Betterbird. Thanks for any help. Phil Payne USA
