Thunderbird stores your data in a separate location, away from the program filesapplication, called your profile folder. To move your data, you can copy your profile folder to the equivalent location on your destination computer.
Note: If you have used the Profile Manager on your source computer to store your Thunderbird profile folder in a custom location into a remote storage drive, create a new profile on your destination computer and set that profile to use the same location. Thunderbird's new installation will use the already existing data.
- On your source computer
- Connect a device for data transfer, either a local one such as a USB flash drive, or a remote storage drive.
- Click the menu button
, then click and select .Open the menu and select .
- Locate the "Profile Folder" entry, then click .

- When prompted, choose to replace your current data.
- An Alternative Method:
- Hold down the Option key while pulling down "Go" on the Mac's main menu. Select and open Library.
- Within the Library is a Thunderbird folder, which can be copied/pasted or Shared (ie. right-click, Share, AirDrop if the receiving computer is in close proximity)
- Ensure you already have the Thunderbird app installed on your receiving computer, but don't open it to check messages. Go through the same process (Option key, Go, Library) and replace the empty (or old) Thunderbird folder on the receiving computer with the existing Thunderbird folder that contains all your current data.
- Test Thunderbird on the receiving computer - it should look identical to your original on the sending computer and contain all the same messages. CAUTION: Do not open Thunderbird again on the original computer - unless you repeat the process in reverse to transfer the folder contents back to the original computer before opening the app. (If you forget, you can manually check one version against the other to ensure important messages are retained, but it's messy and time consuming.)
