I have IE and firefox on my machine. Before using CC Cleaner I usually clear the cache of both browsers first then use the cleaner. When I click analyze, the cache of IE is drastically lower but Firefox is still very high. Why does that happen? It seems like I can't clear the cache in FF or am I doing something wrong?
you need to change Time range to Everything
you can try CTRL+SHIFT+DEL if you can click "clear your recent history"
