Safari is no longer supported on Windows platforms, but the Mac version is constantly updated to ensure optimal performance. Clearing your cookies and cache will only boost this performance. This will prompt a drop-down menu. This will open a window from which you can alter your privacy settings. This should be near the top of the "Preferences" window. From here, you can clear your cache and cookies. Safari will ask you to confirm your decision. This will clear both your cookies and your site cache; if you haven't done this before, you should notice a difference in your browsing speed! You may have to exit out of Safari and re-open it in order for your changes to take place.
