Are you doing it all by hand, or using some Mac/Windows features that are supposed to synchronize your data for you, or using a third party product?

I should mention that this forum focuses on Mozilla products (like Firefox and Thunderbird) so some aspects of this question is probably beyond our scope.

I assume you have installed Firefox and you have a new profile without your settings.

Did you sign in to your Firefox Account to see whether Firefox Sync would transfer your bookmarks, saved logins, etc.? See: How do I set up Sync on my computer?

If Sync does not work:

Do you run Mac, Windows, or Linux?

I can help with Windows.

Profile Transplant Method for Windows-to-Windows

(1) Open Source Folder

Maybe you have a copy of your old computer data on an external hard drive or maybe you have copied it to your computer. What you need is your old profile folder from the path:


AppData is a hidden folder. To make it visible:

The profile folder name is partially randomized, so something like ab43c65z.default-release

Got it?

Open a Windows File Explorer window and drill down until you can see that old profile folder name. Don't click into the folder since we want to copy the whole folder in a later step.

Resize that File Explorer window with the source folder and move it to the left side of the screen.

(2) Open Destination Profiles Folder

Open the receiving Profiles folder using either step-by-navigation, or by pasting a shortcut in the Windows 10 system search box and pressing Enter to launch it:

  • C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles
  • Shortcut: %APPDATA%\Mozilla\Firefox\Profiles

Resize that File Explorer window with the destination folder and move it to the right side of the screen.

(3) Drop a copy of the old profile folder back into the folder Firefox uses for profiles:

In the source folder on the left, right-click the profile folder and choose Copy. Important: copy the folder because you need to transfer the folder. This is not a method where you copy individual files.

In the destination Profiles folder on the right side of the screen, right-click an empty area and choose Paste to paste the folder here.

(4) Configure Firefox to use the old profile

Make a note of the text after the dot on the profile folder. For example, it might be default or default-release. You need the new profile name to match the old one in order for Firefox to regain use of your extensions and their data.

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

  • Click the "Create a New Profile" button, then click Next.
  • Assign the old profile name default and Firefox should show a proposed folder name with a new random part.
  • Click the "Choose Folder..." button and select the old profile folder you copy/pasted so that Firefox picks up the full old name.
  • Back in Firefox, click the Done button.

After creating a new profile, Firefox usually makes it your default profile (for external links and the next startup). To test, scroll down to it and click the Launch profile in new browser button.

Did it work?

If so, you're done.

If not, you can close that window without affecting your regular Firefox profile and change back to the profile you started with before this post. Click the Set as Default Profile button below that profile.
