Saving cache files is mostly a good thing because it improves the overall experience of the browser and the application. However, while your computer will save cache automatically, you will have to manually delete it in most cases.

Cookies consist of your login info for other sites and your browsing history. This is one of the typical pieces of information digital advertisers use to target you for ads.
