I’m running Thunderbird 128.6.0esr (64-bit). I’m trying to export my address book in csv format. I tried to follow these instructions: Start Thunderbird In Address Books Select address book (not 'All Address Books' as it is a virtual search and not a true address book) Tools > Export Choose where to save Save as either: Comma Separated *csv files OR LDIF Click on 'SAve' However, I not finding the option to save as *.csv file. I get abook.sqlite file, but I can’t open file. What app do I use to open file so I can get a *csv file to I can export to use in Outlook. Thanks, John
