What a life saver. I have been a Thunderbird user for many years with emails going back to 2008, I was using an old HP Windows Laptop that finally had to go. I opted to get the new Macbook Air with M1 chip. Now I had to migrate from Windows to MacOS - Big Sur. I had read all the older articles on migration from one OS to another and was dreading it. I gave this add-on a try and it worked as slick as it could. I exported from the laptop to a thumb drive. Then imported on the Macbook from the thumb drive. The file size was over 14Gb. Did not loose an email or attachment. What a life saver. Fantastic add-on to say the least
