What is your computer system and Firefox?

Did you open Firefox and find its data gone? Or did the other program just copy the information?

I've called the big guys to help you. Good luck.

Your meta data says Window 6.1 64 try multiple scanners: Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus built-in already.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.
