I am having the same exact issue. CCleaner Freee version 1.15.507, OS X High Sierra version 10.13.6. I don't get a prompt to close Safari, but it takes almost 15 minutes and makes me type in my password twice in order to clean. Asks for password at /Users/xxxx/Library/Safari/LocalStorage/https_secure-dcr.imrworldwide.com_0.localstorage-wal and /Library/Logs/DiagnosticReports/com.apple.WebKit.WebContent_DATE_computername.wakeups_resource.diag Help please
Hi. I'm not sure if this is still an active issue/thread, but I just upgraded to Windows 10 and found this thread via a google search. I was able to change this behavior (I think) with a setting change and a reboot. Go to Settings -> Privacy -> Background Apps and Turn Microsoft Edge off and reboot. I did so and now CCleaner removes temp files that Edge uses, and kills the running process that CCleaner doesn't stop and thus, skips. Sorry if this has been fixed already.
