Thunderbird saves your personal information such as messages, passwords and user preferences in a set of files called your profile, which is stored in a separate location from the Thunderbird program files. You can have multiple Thunderbird profiles, each containing a separate set of user information. The Profile Manager allows you to create, remove, rename, and switch profiles.
- If you have (or plan to have) multiple installations of Thunderbird on one computer, see Dedicated profile per Thunderbird installation.

If you need to move your Thunderbird data (accounts, messages, passwords and other data) to a new computer, see Moving Thunderbird Data to a New Computer.
Recovering information from an old profile
If you have important information from an old Thunderbird profile, such as bookmarks, passwords, or user preferences, you can transfer that information to a new Thunderbird profile by copying the associated files. For instructions, see Recovering important data from an old profile. You can also switch to a previous profile to recover old profile data.
