CCleaner version 5.27.5976 64 bit version crashes when trying to clean Firefox v51.0.1 "Compact Databases" CCleaner started crashing after an update of Firefox. I tried various settings and finally narrowed it down to Firefox. In Applications / FIrefox section, if I check the Compact Databases, then CCleaner crashes when trying to clean. If I uncheck that box, CCleaner functions OK. It does not affect the Registry cleaning. See attached screen shots CCleanerPro-crashes-v5-27-5976-64bit.pdf
