Copying all your Thunderbird data
You can copy your Thunderbird data to a new computer with a simple 4-step procedure that copies your
profile,
and then tells Thunderbird where to find your profile. In Thunderbird,
your profile is a set of computer files containing your personal
information including messages, passwords and user preferences.
- To find the folder where your profile is stored, from the menu, click then look for Profile Folder, and click on the Open Folder button. This will open a window showing information about your profile folder. In
this window, you will see a path of names, starting with names of
parent folders that contain your profile folder, and ending with the
name of your profile folder. The path will look something like this
example: This PC > Elements(D:) > Other Documents > Amy's Thunderbird Profile
- Use Windows Explorer] to copy your profile folder to a new computer. You can put your profile folder into a parent folder of your choice.
Warning: Do not copy a profile folder while Thunderbird is running and using that profile.
- Open the Thunderbird Profile Manager. For instructions, visit Using Multiple Profiles.
- The Thunderbird Profile Manager displays a list of profiles
recognized by Thunderbird, listed by name. You can think of each name in
the list as a nickname that Thunderbird uses to identify each
recognized profile. Here's an example of the Thunderbird Profile Manager
window:
Proceed to tell Thunderbird to recognize your new profile:
- Click the Create Profile button.
- Click Next.
- Enter a new nickname for your new Thunderbird Profile (this does not need to be the same as the name of your profile folder).
- Click the Choose Folder button,
- Navigate to and select your new location's profile folder.
- Click Select Folder.
- Click Finish.
You will now see your new profile included in the list.
- If each time you start Thunderbird you want to select from a choice of profiles, uncheck the Use the selected profile without asking box.
- To automatically use a specific profile whenever Thunderbird starts, select that profile and check the Use the selected profile without asking box. (You can always open the Choose User Profile window again, to change this setting.)
Your Thunderbird Profile
Your Thunderbird Profile stores everything about your email,
including locally stored messages and attachments, address lists,
account settings, Thunderbird settings, stored passwords, tasks,
calendar data, and data for add-on features. You can keep a profile on
just about any kind of storage or device.
Note: If you want to keep your
Thunderbird data secure, consider making regular backups of your
profile. It's wise to use good judgement about revealing Thunderbird
profile names, folder names and storage locations to others.
Learn more about your profile at
Profiles - Where Thunderbird stores your messages and other user data.
