Thanks Brink for the links, but nothing I tried resolved the issue. The problem was corruption in the registry because of the Firefox 52.5.3 ESR crash. Restoring the last mirror helped temporarily, but with the reinstall of Firefox, the registry corrupted again and affected the Recycle bin. So, I ran JetClean repeatedly until suddenly everything was back to normal.
Caveat: Use a registry cleaner only if you have good mirror backups and keep no data on the boot drive. Macrium has saved my skin on numerous occasions.
