Hi

Do you have a backup of your profile from your old hard drive or your data stored in Firefox on another device?

No. Old hard drive is gone. I was told all the data is on the new hard drive.

So they tossed the drive or what happened to it? It has your private data on it.

This will help if all your data has been transferred or copied to the new drive.

You weren't previously using MSIX Firefox from the MS Store as that version has the profile folder in a different location ?

Primary location used for the main profile that keeps your personal data (Root Directory on about:profiles).

• C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>
