Suddenly was unable to open latest Firefox version on latest version of Windows 10 for desktop. Have concluded problem due to corrupt "places.sqlite" file after reinstalling a fresh copy of latest Firefox version for Windows and was not able copy old profile contents over new profile folder due to Windows error "Can't read from source file or disk". In addition all bookmarks, history, etc. data missing. Note: Do not know if this is relevant, two additional "places.sqlite" file variations found within old profile folder: places.sqlite-shm places.sqlite-wal How can I recover all my lost data? Thank you!
