Hey there! I had to refresh my computer and didn't realize I would lose my address-book. So now I have the newest version of thunderbird and thousands of emails newly downloaded, but nothing in my address-book. I'd love to send emails to people just by starting to type their name again, instead of hunting for old emails sent by them.. I found there are add-ons like address-crawler or Incoming Addresses Collector, but they seem to not be compatible with the new thunderbird. Is there an alternative to reinstalling an old version of thunderbird, downloading all the emails again, using the addons, export them into the new version? Thank you!
