Firefox saves your personal information such as bookmarks, passwords, and user preferences in a set of files called your profile, which is stored in a separate location from the Firefox program files. You can have multiple Firefox profiles, each containing a separate set of user information. The Profile Manager allows you to create, remove, rename, and switch profiles.

If the Profile Manager window still does not open, Firefox may have been running in the background, even though it was not visible. Close all instances of Firefox or restart the computer and then try again.

After starting the Profile Manager as explained above, you can create a new, additional profile as follows:

  1. In the Profile Manager, click Create Profile... to start the Create Profile Wizard.
  2. Click Next and enter the name of the profile. Use a profile name that is descriptive, such as your personal name. This name is not exposed on the Internet.

  3. You can also choose where to store the profile on your computer. To choose its storage location, click Choose Folder....
    Warning: If you choose your own folder location for the profile, select a new or empty folder. If you choose a folder that isn't empty and you later remove the profile and choose the "Delete Files" option, everything inside that folder will be deleted.
  4. To create the new profile, click FinishDone.

You will be taken back to the Profile Manager window, where you can either start Firefox or exit the Profile Manager.

Note: If you want the Profile Manager to appear the next time you start Firefox, remove the checkmark from the box, "Use the selected profile without asking at startup". Otherwise, the selected profile will be used automatically.

When you first start Firefox with the new profile, you will be prompted to sign in to your Firefox Account so that you can sync your data with the new profile (see below).

Removing a profile

After starting the Profile Manager as explained above, you can remove an existing profile as follows:

  1. In the Profile Manager, select the profile to remove, and click Delete Profile....
  2. Confirm that you wish to delete the profile:

    • Don't Delete Files removes the profile from the Profile Manager yet retains the profile data files on your computer in the storage folder, so that your information is not lost. "Don't Delete Files" is the preferred option because it saves the old profile's folder and allows you to recover the files to a new profile.
    • Delete Files removes the profile and its files, including the profile bookmarks, settings, passwords, etc.
      Warning: If you use the "Delete Files" option, the profile folder and files will be deleted. This action cannot be undone.
    • Cancel interrupts the profile deletion.

Renaming a profile

After starting the Profile Manager as explained above, you can rename a profile as follows:

  1. In the Profile Manager, select the profile to rename, and then click Rename Profile....
  2. Enter the new name for the profile. Type in the new profile name, and click on OK.
    • Note: The folder containing the files for the profile is not renamed.

Manage profiles when Firefox is open

Type about:profiles into the Firefox address bar and choose from the following options:

Fx52aboutprofiles-Winabout:profiles macOS Fx52_about-profiles-linux
  • Create a new profile: Click Create a New Profile and follow the steps in the Creating a profile section above. After you finish creating the new profile, it will be listed in the Profile Manager. Select the Set as default profile option underneath that profile, if you want Firefox to use your new profile the next time you start Firefox.

To manage profiles, find the profile you want to change and choose from these buttons underneath that profile:

  • Rename: Click this to change the name of a profile in the Profile Manager. Note: The folder containing the files for the profile is not renamed.
  • Remove: Click this to delete a profile. (The profile in use cannot be deleted.)
    Warning: Due to a bug, the profile folder and its contents will be deleted, even though you choose the "Don't Delete Files" option. This action cannot be undone. If you want to remove a profile but keep the files, start the Profile Manager with Firefox closed. See the Removing a profile section above for more information.
  • Set as default profile: Click this to make Firefox use this profile at startup, unless you switch to a different profile.

  • Launch profile in new browser: This option is not used to manage profiles. It's intended for advanced users who have launched Firefox with a special startup command.When you click this button, another Firefox window will open using that profile.When you click this button, another Firefox window will open using that profile.

Options

These options are only available when you start the Profile Manager when Firefox is closed.

Work Offline

Choosing this option loads the selected profile and starts Firefox without connecting to the Internet. You can view previously viewed web pages and experiment with your profile.

Use the selected profile without asking at startup

When you have multiple profiles, this option tells Firefox what to do at startup:

  • If you check this option, Firefox will automatically load the selected profile at startup. To access other profiles, you must start the Profile Manager first.
  • If you uncheck this option, Firefox will show you the Profile Manager each time you start Firefox, so that you can select a profile to use.

Use Sync with a new profile

FxNewProfile-SyncSigninNew Firefox Install - macOS

When you first open Firefox with a new profile, you will be prompted to sign in to Sync, which allows different Firefox profiles to share the same bookmarks, browsing history, passwords and other user data.

  • If you already use Sync in another profile or device, enter the email address and password for your Firefox Account and your new profile will use those settings.
  • If you don't use Sync or if you don't want to sync your data with the new profile, you can skip this step.

See How do I choose what information to sync on Firefox? and How do I set up Sync on my computer? for more information.

Moving a profile

To copy all of your Firefox data and settings to another Firefox installation (e.g. when you get a new computer), you can make a backup of your Firefox profile, then restore it in your new location. For instructions, see Back up and restore information in Firefox profiles.

Recovering information from an old profile

If you have important information from an old Firefox profile, such as bookmarks, passwords, or user preferences, you can transfer that information to a new Firefox profile by copying the associated files. For instructions, see Recovering important data from an old profile.
