Hi, I am new here, and am just switching to Mac. After logging out to my email account, and cleared history by using the History tab. However, when I moved the page back by using two-finger swipe to the left, my previous pages of my Inbox and my emails still showed for about two seconds. Is there any way to really clear the history, so no one can see anything by using the using the finger-gestures? I do not want someone (just in case) who happens to use my Mac after me to see those pages.
