If you moved, renamed, or deleted your Firefox profile folder

Firefox stores your user data and settings in a special profile folder and pulls information from this folder every time you start Firefox. The default profile folder location is under the ~/Library/Application Support/Firefox/Profiles folder, which you can find using these instructions.

A Profile was moved or renamed

If you know where your profile is, try one of the following methods to help Firefox find it.

  • Move the profile folder back to its original location.
  • Restore the profile's original name if you've changed it.
  • Create a new profile using the Profile Manager. Give it a descriptive name, click on the Choose Folder button, and then select the profile folder you moved or renamed, before you finish the Create a new profile wizard.

Profile was deleted

If you deleted or lost your profile folder and have no way of restoring it, use one of these methods to create a new Firefox profile:

Your new profile will not contain settings or user data from your deleted or lost profile.
  • Method 1: Use the Profile Manager wizard

Follow the steps in the Use the Profile Manager to create and remove Firefox profiles article to create a new profile.

  • Method 2: Manually delete the profiles.ini file

If you have problems accessing the Profile Manager, you can create a new default Firefox profile by deleting the profiles.ini file, using these steps:

  1. Navigate to your user ~/Library folder:
    • (OS X 10.6) Click the Finder icon in the dock. Your home folder will be selected, (usually the name of your Mac user account). In the right side of the window, click the Library folder to open it.
    • (OS X 10.7 and above) Click the Finder icon in the dock. On the menu bar, click the Gomenu, hold down the option or alt key and select Library. A window will open containing your Library folder.
  2. Click on the Application Support folder, then go to the Firefox folder.
  3. Delete (or rename, for example, to profiles.iniOLD) the profiles.ini file.
Note: Instead of deleting the profiles.ini file, you can delete (or rename) the folder that contains it. For example, rename the Firefox folder to FirefoxOLD.

When you start Firefox, a new profile will be created.
