Best is to use the Profile Manager to create a new profile folder if you previously replaced all file in the profile that Firefox created with the files of your backup.

You can copy certain files with Firefox closed to the current profile folder to transfer or recover personal data. Note that best is to avoid copying a full profile folder.
