Cookie 是您访问的网站保存在您的网络浏览器中的数据片段。第三方 cookie 是由您想访问的网站以外的网站创建的。大多数情况下，第三方 cookie 被广告服务使用，它们希望根据您的浏览历史和网络搜索为您提供有针对性的广告。但是，这些 cookie 可能会引发隐私问题，因为它们还可用于存储您在使用相同广告服务的网站上的浏览历史记录。这就是为什么诸如“第三方 cookie是否存在安全风险？”之类的问题。(Are)或“阻止第三方 cookie 好不好？” 经常出现。为了帮助您，在本文中，我们将向您展示如何在Chrome、Firefox、Edge和Opera，涵盖当今所有主流浏览器。事不宜迟，以下是关闭第三方 cookie 的方法：
阻止第三方 cookie：这是什么意思？
当您访问包括Digital Citizen在内的网站时，它通常会在您的网络浏览器的帮助下在您的计算机上存储至少一个cookie 。该网站使用其 cookie 来保存有关您的访问和偏好的信息，以便您可以毫无问题地浏览它。
大多数网站还在您的设备上存储由其他网站和服务创建的第三方 cookie。例如，网站使用的一些最常见的第三方 cookie 来自：
- Google Analytics - 用于分析网站流量的第三方 cookie
- Google AdSense或Doubleclick - 用于在您访问的网站上投放广告的第三方
- Facebook - 第三方 Cookie，用于让您访问“赞”(Like)或“分享(Share)”按钮或嵌入来自Facebook的不同类型的内容(Facebook)
来自数字公民的 Cookie
在您的网络浏览器中阻止第三方 cookie 可以阻止广告商和其他实体的跟踪。那么，阻止第三方 cookie 好不好？是的，它可能是好的，但也可能是坏的：阻止 cookie 可以增加您的隐私，但它也可能破坏您访问的某些网站。
在我们向您展示如何禁用第三方 cookie 之前，请记住，如果您在隐身模式下(incognito mode)使用第三方 cookie，大多数网络浏览器已经关闭它们。此外(Furthermore)，一些网站还会监听您的浏览器发送的DNT（Do Not Track ）请求（(Track)如果您启用了 DNT 设置(if you enabled the DNT setting)），这意味着它们可能已经禁用了可以跟踪您的 cookie。

How to block third-party cookies in Chrome, Firefox, Edge, and Opera
Cookies are pieces of data that are saved in your web browser by the websites you visit. Third-party cookies are created by a website other than the one that you wanted to visit. Most of the time, third-partу cookies are υsed by ad services that want to offer you targeted ads bаѕed on your browsing history and your web searches. Howеver, these cookies can raise privacy concerns, as they can also be used to store your browsing history acroѕs websites that usе the same ad services. That’s why questions like “Are third party coоkies a security risk?” or “Is it good to block third party cookies?” often arise. To help you out, in this article, we’re going to show you how to disable third-party cookies in Chrome, Firefox, Edge, and Opera, covering all the major browsers today. Without further ado, here’s how to turn off third-party cookies:
Blocking third-party cookies: What does it mean?
When you visit a website, including Digital Citizen, it usually stores at least one cookie on your computer with the help of your web browser. That website uses its cookie(s) to keep information about your visit and your preferences, so that you can browse it without issues.
Most websites also store third-party cookies on your devices, which are created by other websites and services. For example, some of the most common third-party cookies used by websites are from:
- Google Analytics - third-party cookies used for analyzing the traffic of the website
- Google AdSense or Doubleclick - third-party used to deliver ads on the website you visit
- Facebook - third-party cookies used to give you access to Like or Share buttons or to embed different types of content from Facebook

Blocking third-party cookies in your web browser can block tracking from advertisers and other entities. So, is it good to block third-party cookies? Yes, it can be good, but it can also be bad: blocking cookies can increase your privacy, but it can also break some of the websites you visit.
Before we show you how to disable third-party cookies, keep in mind that most web browsers already turn off third-party cookies if you use them in incognito mode. Furthermore, some websites also listen to DNT (Do Not Track) requests sent by your browser (if you enabled the DNT setting), which means that they might have already disabled the cookies that can track you.
How to block third-party cookies in Google Chrome
To disable third-party cookies in Chrome, first, click or tap on the “Customize and control Google Chrome” button from the browser’s top-right corner. It looks like three dots arranged vertically. In the menu, select Settings.
Open Settings in Google Chrome
Scroll down and click or tap on “Cookies and other site data” under “Privacy and security.”

Why did you choose to block 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 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 your experience after doing that.
