How To Manage Profiles

Mozilla Thunderbird stores all your personal settings, such as your mail, passwords and extensions, in a profile. The profile is stored on your hard drive in a profile folder.

If you run into problems using Thunderbird (e.g. problems starting after installing an extension, or other features not functioning properly), the first thing you are usually asked to do in the tech support forum is to create a new profile. This tutorial will not only show you how to do that, but, also, how to create backups and move or restore existing profiles.

In order to create a new profile, you use the Profile Manager. To start the Profile Manager in Windows, follow these steps:

  • Close Thunderbird completely (select File > Exit from the main menu of Thunderbird).
  • Select Start > Run... from the Windows Start menu.
  • Enter thunderbird.exe -profilemanager and press OK.

    - (On Mac OS X, hold down the Option key and double click the Thunderbird icon.)
    - (On Linux, start Thunderbird with the the -profilemanager switch, e.g. ./thunderbird -profilemanager (this assumes that you're in the Thunderbird directory).)

You should now see the Profile Manager window.

Note: From the Profile Manager, you are also able to remove and rename profiles.

  • Click on the Create Profile... button to start the Create Profile Wizard.
  • Click Next and enter the name of the profile, e.g. your name or something descriptive. You can also choose where on the disk you want the profile to be stored, which is useful if you plan on exporting your settings to another computer or setup in the future.
  • click Finish to have Thunderbird create the new profile.

The Profile Manager

You should now be taken back to the Profile Manager and the newly created profile should be listed. Select it and click Start Thunderbird. That's it!

You are now running Thunderbird with the new profile, which means all settings are reset to default. If you want to switch back to your old profile, just start the Profile Manager again (instructions above) and select the old profile.

You can also have Thunderbird start a selected profile automatically, so you don't have to pick one each time the browser is launched. Do this by checking the Don't ask at startup option.

Backing up your profile

Backing up your profile folder in Thunderbird is easy. Just follow these steps (which assumes you know how to manage files on your computer):

  • Shut down Thunderbird completely (File > Exit).
  • Make a copy of your profile folder to, for example, a CD-RW disc or a separate hard disk for backup purposes.
  • Move an existing profile or restore a backed up profile.

It is possible to move the location of a profile folder. This could be useful if you have a backed up profile folder somewhere on your hard drive and want to tell Thunderbird to use that as your profile. This section explains how to do this:

  • Shut down Thunderbird completely (File > Exit).
  • Move the profile folder to the desired location. For example, on Windows, move the profile from C:Documents and Settings[username]Application DataThunderbirdProfilesxxxxxxxx.default to D:StuffMyMailProfile. If you are reading these instructions because you want to restore a previously backed up profile, this step isn't necessary. Just note the current location of the profile you want to restore.
  • Open up profiles.ini in a text editor. The file is located in the application data folder for Thunderbird:
    - On Windows XP/2000, the path is %AppData%Thunderbird
    - On Windows 95/98/Me, the path is usually C:WINDOWSApplication DataThunderbird
    - On Linux, the path is ~/.thunderbird/
    - On Mac OS X, the path is ~/Library/Application Support/Thunderbird/
  • In profiles.ini, locate the entry for the profile you've just moved. Change the Path= line to the new location.
  • Change IsRelative=1 to IsRelative=0.
  • Save profiles.ini and restart Thunderbird.
