8. After the reset is finished, your old Firefox profile information will be placed on your desktop in a folder named
Old Firefox Data. If the reset didn't fix your problem you can restore some of the information not saved by copying files to the new profile that was created. See
Copying files between profile folders for instructions. If you don't need this folder any longer, then you should
delete it as it contains your sensitive information.
That's it,
