This add-on is the only way I have found to import my Thunderbird emails on Windows XP to my new Thunderbird on Windows 8.1. It works great for this task, although why Mozilla's Thunderbird should require an add-on to import its own emails when it can do Microsoft's Outlook automatically is difficult for me to understand...
