How to Move Thunderbird to Another Computer

It is very similar to moving Firefox to another Computer.

  1. Run a new installer of Thunderbird on the new computer, in this case 38.1.0. On my old computer I had in use version 31.7.0
  2. Locate the Thunderbird profile folder on the old computer. For this, open menu-help-troubleshooting information-profile folder-show folder.
  3. The content of your profile folder will be shown in an explorer. The name of the folder will probably something cryptic like 6wm13muk.default and the location somwhere below AppData.
  4. Locate the Thunderbird profile folder on the new computer.
  5. Close Thunderbird and empty the profile folder on the new computer.
  6. Copy the content of the profile folder from the old PC into the profile folder on the new computer.
  7. Done. This worked perfectly for me. All settings, connections, mails and addresses all the addons with all their settings are used on the new computer now.

Time needed: 5 minutes for finding the solution on the internet, 5 minutes for executing it. Next time I’ll be 5 minutes faster 🙂
