I am using 1.0 RC1. I cannot import my text based address books into the mail client. Doesn't matter if I use CSV or .txt files. The import starts. I get a small gray block that has non-functioning scroll bars and it says 'field' 'next' but when I hit proceed, it says it imported the text info successfully, but the address book is empty. I even tried making .csv and .txt files with Excel to test the import that way and no dice.
Actually - there is NO DATA in the little import window. I know the source files I am using to try and populate the addressbook are good. I scroll from record to record and nothing seems to be there in the import utility.

Verified Fixed. The latest Mozilla trunk and branch builds should work.
