I use FireFox and DuckDuckGo search. I use Ccleaner. I kept noticing that the Button for Google Signed-out search activity was being automatically turned on. Through process of elimination, I found that I need to put google.com in the Ccleaner Cookies to Keep column to stop the button from being turned on. I have never allowed Google cookies to remain in place. Is there any other way of preventing Google from monitoring my search when I am not signed in to a Google account?
