How to clean cookies
Why you should clean cookies
Every time you visit a website, it will look for its cookie on your hard drive. It uses the information stored within the cookie to know your name, your shopping preferences, etc.
Despite cookies are useful, they can also store such information as your name and password on protected login pages, preferences, account information and choices you have made on the website. And even if you clean browser history, cookies like a map will show your surfing preferences, habits, passwords, etc. Even if the cookies don't contain such information they clearly show that you visited the websites from which they came. So to protect your privacy, you should constantly clean cookies.
Also in one of their malevolent forms, cookies from one web site might track your visits to a different web site. For example, most of the ads that you see on web sites do not come from the website that you are viewing, but from websites that provide ads to many sites. When the advertising site displays the ad, it can send cookies on your computer. This lets the advertising company track your web usage over a range of sites and profile your browsing habits.
