Mozilla Thunderbird and Windows Live Mail

I had a computer that was running Windows Vista.  I was using Mozilla Thunderbird and Windows Live Mail for email.  I used Norton 360 for backup.  The computer crashed.  I purchased a new computer that is running Windows 8.1.  I did a restore from Norton 360 and re-installed Mozilla Thunderbird and Windows Live mail.  I have not been able to find my Mozilla Thunderbird files, contacts or email and I have not been able to find my Windows Live Mail contacts, I was able to locate the Windows Live Mail emails.  Any help would be greatly appreciated.

Thanks,

Bob
