If you want to replace individual files instead of trying to use the entire old folder, here's how you can open the current folder. First, though, open this page for reference in a different browser:

Recovering important data from an old profile

Open your current Firefox settings (AKA Firefox profile) folder using either

  • "3-bar" menu button > "?" Help > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table on the page, on the Profile Folder row, click the "Open Folder" button. This should launch a new window listing various files and folders in File Explorer.

Leaving that window open, switch back to Firefox and Exit, either:

  • "3-bar" menu button > Exit
  • (menu bar) File > Exit

Pause while Firefox finishes its cleanup, then you can start replacing the current files with the backup files.

Start Firefox back up again. Does it show the data from the files you copied over?


If you want to use the entire old folder, first set Windows to show hidden files and folders:

https://support.microsoft.com/en-us/help/14201/windows-show-hidden-files

Firefox Profile folders should be here:

C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles

You can drop a copy of the old folder here alongside the current one. Then the next step is to get Firefox to recognize that it is present. There are various methods for this but I have to leave the keyboard so more on that later if needed.

If you left the backup on the same hard drive you formatted, then it's gone as everything is removed.

Hi,

No. I have a backup of the profiles folder on a different hard drive but the problem is that I didn't do the backup via the "Import and Backup" tool.

But the question is, can I recover the data (cookies, bookmarks, etc) from having only the folder itself?

Does anyone familiar with the issue and can help please?
