Hi

Do you have your user credentials and bookmarks on your other device you were using Firefox Sync with?

No, I was logged off from another device as well.

It was original device and I reset windows so I lost all my saved passwords. When I reset password all files and bookmarks were lost.

Do you have an "Old Firefox Data" folder on your desktop? Is there a "Windows.old" in your root directory (C:/)? Be sure that you don't delete either one.
