Let’s begin by first understanding what a browser cookie is.

What are Browser Cookies?

Browser cookies (also called web cookies, internet cookies, and HTTP cookies) are tiny pieces of data created whenever you browse the internet. They’re used to identify your computer when you’re on a network. This lets the network server identify your device and provide you with specific information. 

I’ll explain it in a very simple manner. Whenever you visit a new website, a cookie is created. This cookie contains information about your internet session and is stored by your web browser. And when you visit that website again in the future, the website reads the cookie and remembers your previous session activity so that you can resume your session without starting all over.

What Do Browser Cookies Do?

Here are the three main functions of browser cookies. 

1. Session Management 

Cookies allow websites to remember users and recall information like login details and preferences. E.g. Cookies help you to access websites without having to enter your username and password every single time. 

2. Personalisation 

Cookies allow custom advertisements to be shown to you based on your internet history. This ensures that you are only shown ads for relevant content that you might be interested in.

3. Tracking 

Many shopping websites (Amazon, Flipkart, etc) use cookies to track the items you view on their website so that they can show you recommendations for similar items. They also keep items in your shopping cart saved, so that even if you reopen the session at a later time, your items will still be there.

What Is The Difference Between Browser Cookies And Caches?

You might have heard the words cookies and caches used a lot, and sometimes they are even used interchangeably. However, they are both completely different. A cache is used to store online page resources for your browser so that it loads faster in the future. A cookie, on the other hand, stores your user choices and login details to provide you with a more personalised user experience while surfing the web.

Why Cookies Can Be Dangerous

I’ve taken you through the benefits of having cookies. But there’s a flip-side to this. Browser cookies can also be dangerous to you and your device, as your personal information is being stored.

Cookies by themselves are harmless since they’re just bits and pieces of data. But since they can track your browsing history, it becomes a cause for concern. 

Let’s say you’re browsing a website and there are ten advertisements on the page. These advertisements will generate ten different cookies for your system, even if you don’t click them. These are called third-party cookies, and there are chances of these cookies being hijacked by a cyber-attacker to gain access to your internet sessions and browsing activity.

Cookies also take up space on your hard drive. As you surf more and more websites, there are hundreds of cookies that are being saved every day. Unless they are deleted, they’ll clutter up your system and lag your browser.

The biggest concern of all is privacy. I’m sure you value your internet privacy, just like most people. Browser cookies allow websites to monitor all your online activity and sometimes you might not even be aware of it! This is why it’s important that you regularly delete your browser cookies.

How Often Should I Delete My Browser Cookies?

It’s never a good idea to have cookies saved on your computer for long periods of time. Since there are a lot of third-party cookies that get inadvertently saved in your browser, advertisers and malicious entities will continue tracking your online activity and get access to your personal data.

On your personal PC or device, it is recommended to clear your browser cookies once a month. But if you’re using a shared PC, one that is used by other family members or friends, you should clear your browser cookies as soon as you finish an internet session. If you don’t, the next person on that PC to visit the same websites that you have visited will get access to your login information. Make sure you delete your cookies before closing the browser!

Cookies can accumulate over a long period of time and cause lags in your browser performance. If you notice such lags or performance dips, make sure you delete your cookies to rule it out as a possible reason.
