CCleaner keeps reporting cleaning of browser while not in use

Numerous displays of cleaning the browser are shown on desktop when the Firefox browser is not in use. In addition, notification is displayed and seems to freeze on desktop until I clear it away. In the past the notification would display for five seconds and disappear.

CCleaner Version in use is 5.75.8238
