Disable third-party cookies in Chrome, Firefox, Edge, Opera and Internet Explorer

Third-party cookies are pieces of data that are saved in your web browser by the websites you visit. However, their origins are on other domains. Most of the time, third-party cookies are used by ad services to offer you targeted ads that are based on your browsing history and your web searches. However, these cookies can raise privacy concerns as they can also be used to store your browsing history across websites that use the same ad services. This is the reason why, in this article, we will show you how to disable third-party cookies in all the major web browsers for Windows: Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, and Internet Explorer. Let's get started:

What does it mean to block third-party cookies?

When you visit any website, including Digital Citizen, at least one cookie is stored on your PC by your web browser. This cookie is used to store details about your visit and your preferences so that you can browse the website without issues.

Most websites also store third-party cookies on your PC, from other websites and services. For example, they may use Google Analytics (used for analyzing the traffic of the website), Google AdSense (used to deliver ads on the website that you are visiting) and Facebook (used to provide you with access to like buttons or share buttons). Disabling third-party cookies in your web browser can stop some types of tracking by advertisers and other third-party entities. This increases your user privacy and security.

How to disable third-party cookies in Google Chrome

In Google Chrome, click or tap on the "Customize and control Google Chrome" button from the top right corner of the window. It looks like three dots arranged vertically. In the menu that opens, go to Settings.

Now you have two options: click or tap Settings, in the top-left corner, or Advanced, on the bottom of the window.

If you pressed Settings, then expand Advanced and click or tap "Privacy and security," in the menu on the left.

If you click Advanced, scroll down to "Privacy and security." Finally, no matter which way you chose to get here, click or tap "Content settings."

You see a long list of permissions, split by type. Choose Cookies.

Now you see settings for how Google Chrome handles cookies. Set the "Block third-party cookies" switch to On, like in the screenshot below.

Close the Settings tab and, from now on, Google Chrome blocks all third-party cookies.

How to block third-party cookies in Mozilla Firefox

In Mozilla Firefox, click or tap the Menu button in the top-right corner. It looks like three parallel lines. In the menu that opens, choose Options.

In the Options tab, choose "Privacy & Security" on the left. On the right, look for the "Cookies and Site Data" section.

You see that Firefox is set by default to "Accept cookies and site data from websites." Click or tap the "Accept third-party cookies and site data" drop-down box, and choose Never.

Close the Options tab, and Mozilla Firefox now blocks third-party cookies.

How to disable third-party cookies in Microsoft Edge

Open Microsoft Edge and click or tap on the "Settings and more" button from the top right side of the window. Alternatively, you can press ALT+X on your keyboard. In the menu that opens, choose Settings.

In the Settings panel, scroll to the bottom, and press the "View advanced settings" button.

Here, look for the Cookies drop-down menu, and click or tap on it. You can see that Microsoft Edge is set so that it does not block cookies.

In this menu select "Block only third-party cookies."

Click anywhere outside the Advanced settings pane, and you are done. Microsoft Edge now blocks third-party cookies.

How to disable third-party cookies in Opera

In Opera, click or tap the "Customize and control Opera" button on the top-left corner that looks like the letter O. In the menu that opens, click or tap Settings.

In the Settings tab, choose "Privacy & security" in the column on the left. Then, on the right, find the Cookies section.

In the Cookies section, check the box that says "Block third-party cookies and site data."

You can close Settings, and continue your browsing with Opera.

How to block third-party cookies in Internet Explorer

In Internet Explorer, click or tap the Tools button from the top-right corner (the little gear). You can also use the ALT+X keyboard shortcut to open this menu. Then, choose "Internet Options."

Go to the Privacy tab, and click or tap the Advanced button.

The "Advanced Privacy Settings" window opens. In the "Third-party cookies" section, check Block and press OK.

Close the Internet Options window and you are done. Internet Explorer now blocks third-party cookies.

What is your reason for blocking third-party cookies?

While blocking all third-party cookies may make your browsing history and data more private, it does not mean that all ad networks and third-party services will stop tracking you. Some of them have dodgy methods for tracking visitors on different websites. However, you should see fewer targeted ads, and ad networks and social networks will know a little bit less about you. Before closing this tutorial, we would like to know your reason for blocking third-party cookies and what your experience was after doing that.
