How to Clear Cookies in Most Popular Browsers on Desktop & Mobile?

Internet cookies, also commonly known as Browser Cookies or HTTP Cookies are the piece of information that a website saves on your computer. Different web browsers have different instruction for deleting cookies. But before we see how to clear cookies, it’s important to understand what are cookies, types and why you need to clear cookies on a regular basis.

Cookies are nothing more than some bits of text that a site collects on your computer to identify you whenever you visit that particular website next time.


Internet cookies are helpful especially for e-commerce websites since they help in remembering your cart and purchases. But cookies might pose security issues, which makes it essential for users to delete them on a regular basis.

What are Cookies?

Internet cookies are the text files that your web browser stores on local memory or disk of any smart device or computer. The browser cookies contain small information which is helpful for any website when it visited time and again.

The information could be something like a user ID or a session ID. If a website saves cookies in your system, then only that particular website can access it. No other sites can obtain this information as they belong to some other websites.

The best real-time example of cookies is the online shopping websites or the e-commerce stores. We all do online shopping nowadays, but have you ever give it a thought that how the site remembers the items you last viewed or the items in your cart or wish lists? Well, the answer to this question is cookies.

How Cookies Work?

All the cookies are stored in your computer system and are managed by your web browser. You can easily find the list of websites that have stored the cookies on your web browser and can also have a look at the cookies.

All browsers have their list of cookies. If you use multiple browsers for internet surfing, then each one of that browser will have their separate cookie list.

As we have already discussed, a website is only able to access the cookies that it has saved and has no access to the cookies saved by the other sites. This point is critical here as if this is not the case; then it would have compromised the security of the user’s accounts on various websites.

Websites match the information present in the cookies to validate the identification of the user and thus plays a vital role in browsing.  Cookies can do the following mentioned tasks –

  • It enables customer logins
  • It retains customer information like – payment methods, card numbers, address, etc. (in case of shopping websites)
  • Improves product recommendations
  • Retains your wish lists
  • Retains your shopping cart
  • Search related advertisements, etc.

Example – Going with the above example – when you visit some online shopping store for the first time and register yourself, then the website saves the cookies on your computer system.

From now onwards, whenever you visit that website again, it will identify you using the cookie, and as it recognizes you, it will retain all the item details that you last viewed or added to your cart.

Types of Cookies

Cookies are divided into two categories as session cookies and persistent cookies.

Session Cookies

These are the type of cookies which saves the session ID type of information into your browser. They don’t have a fixed lifespan. These types of cookies will stay in the browser until the session is ongoing.

When the browser has been closed, the cookies will be destroyed. Now when you re-open the browser and re-visit that particular website, it will consider you as a new visitor, and you have to enter your login credentials every time you do so.

Persistent Cookies

Persistent cookies are the ones which have some designated lifespan and have nothing to do with the session. These are the type of cookies which will remain in the browser until their period elapse, or it is deleted by the user manually.

In this case, even if you close the browser, the website will remember you and will not treat you as a new visitor. Also, it will not ask for the login credentials, until you have not logged out, before closing the browser.

Pros of Cookies

  • It helps the website in remembering and identifying you
  • It stores the login state of the user
  • You will not be able to change settings and make them persist in between page loadings unless you have cookies
  • It helps websites in delivering personal content
  • Cookies also retain your information

Cons of Cookies

There are tracking cookies, which keeps on following you all across the web. Advertising networks use tracking scripts which saves a cookie in your browser, and whenever you visit any website that is also using tracking scripts, it will get to know that the same person has visited both the sites.

This tracking cookie also leads to the advertising the similar or recommended products, that you have searched for, on the websites which has nothing to do with it.

You must have noticed some educational website displaying the advertisements of the similar kind of boots that you have been searching for since last few days.
