The unwanted and unwarned Firefox 46.0.1 refresh deleted: Settings, bookmarks, and history but there is no, "Old Firefox Data" folder anywhere. I've checked my laptop twice including Protected Operating System files and hidden files. Is there anyway to get my old data back? Where is the old data file?
