Is there a reason you did the refresh?


Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

You could try the "transplant" method:

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

Let's say your old folder is: abcd1234.default-release

Set Windows to show hidden files and folders: https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

Open this 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

In Old Firefox Data, right-click the profile folder (abcd1234.default-release or whatever) 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 C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles folder, right-click an empty area and choose Paste to paste the folder here.

(2) Configure Firefox to use the old profile

Make a note of the text after the dot on the profile folder. In this example, it's 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-release (or whatever yours is) 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 your fresh profile.
