The problem is that I cannot access any info on my old hard drive...and Im not sure that I even created a profile.  ??

Firefox automatically creates a Profile the first time it is used; so you do have a "Profile".

How are you trying to access the data on your old hard drive?
Do you have a USB to IDE or SATA adapter cable to allow you to connect the old hard drive to a USB port on the new PC?

You always have a Firefox profile folder. Firefox creates one automatically for you the first time you start Firefox.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Director: Show Folder (Linux: Open Director; Mac: Show in Finder)

The "AppData" folder in Windows Vista and later Window 7+ versions and the "Application Data" folder in XP/Win2K are hidden folders.
