CC Cleaner shows activity in Microsoft Edge and Chromium despite not using them
I use FireFox exclusively and employ CC Cleaner to keep internet cache sizes manageable and to clear cookies. When over I run CC Cleaner in addition to the file deletions from FireFox there are also files being deleted from MS Edge and Chromium. How is this possible if I never use either of those browsers? How do I prevent the MS browsers from attaching themselves to FF and in essence overriding my quest for privacy?
