How to clear cookies on Chrome, Firefox, Opera, and other browsers

Every website you visit has a treat for you – cookies. Real-life cookies are delicious, but online “cookies” serve quite a different purpose. Some improve your browsing experience, but others are eager to invade your privacy. Let’s find out how to delete cookies and manage our cookie preferences for the future.

How to clear cookies on Chrome, Firefox, Opera, and other browsers

So what exactly are cookies?

Cookies — also known as internet cookies, web cookies, or HTTP cookies — are small text files containing data about your interaction with a website. When you visit a website, it gives you a cookie that recognizes you as a user.

But don’t get terrified just yet – cookies contain very little data, and can’t identify you personally on their own. They typically include:

  • The name of the website domain that sent the cookie;
  • The cookie’s expiration date;
  • A randomly generated unique number that helps identify you as a returning user.

Different flavors, or rather, types of cookies

Types of cookies

Web cookies vary in terms of their purpose and working mechanisms. The most common cookies are session cookies, permanent cookies, and third-party cookies.

Session cookies

Session cookies, also known as temporary cookies, are stored in temporary memory and don’t have an expiration date. This type of cookie is created when a user enters a website and they only serve for as long as you browse on that page. The cookie is permanently deleted when you close the web browser. Session cookies don’t collect any information from your device, so they don’t really cause any harm to your privacy.

Permanent cookies

Permanent cookies help a website remember and identify you on subsequent visits. Hitting “Keep me logged in” on a website is possible thanks to persistent cookies. They handle user authentication so you don’t have to re-enter your login credentials if you repeatedly visit a specific site. Persistent cookies also help websites remember various settings like your preferred language, theme, or what you left in your shopping basket.

Permanent cookies are convenient. However, for privacy and security reasons, it’s better to disable them. If hackers breach the website or your device, permanent cookies could reveal your personal data.

If you want to know how to delete persistent cookies, check if your browser has an option to delete cookies after each session. As you’ll see below, this feature is available on most modern browsers.

Third-party cookies

These cookies are mostly used for cross-site user tracking. The data they gather is then used by advertisers to serve you targeted ads. They usually appear on websites that have external content or sources, like ads and banners leading to other websites. The domain attribute in a native website cookie is the same as the website’s domain you see in the browser’s address bar, while third-party cookies have a different domain.

Supercookies

Supercookies are super for a reason: they can be embedded on your device without your knowledge, and it’s nearly impossible to delete them. Further, they can contain information including browsing history, authentication details, and ad targeting data. They are the most malicious of them all.

Do cookies cause any harm?

Not to be confused with viruses, cookies are rather innocent – but only until they compromise your privacy. With marketing techniques getting more and more sophisticated, cookies can also become aggressive and collect information about your internet browsing habits. In rare cases, they can also be hijacked by hackers. If you don’t like the idea of being tracked and traced, you should delete your cookies and block any future ones.
