网络犯罪分子总是想出新的方法来劫持您的系统。因此，安全的网页浏览体验对于避免您的个人信息泄露是必要的。Mozilla Firefox等浏览器开发了一种强大的机制来解决这个问题——增强跟踪保护(Enhanced Tracking Protection)。它的更新版本ETP 2.0保护您免受称为(ETP 2.0)重定向跟踪保护(Redirect Tracking Protection)的高级跟踪技术，也称为“反弹跟踪(Bounce Tracking)”。让我们看看如何在Firefox的增强跟踪保护 2.0中启用或禁用(Enhanced Tracking Protection 2.0)重定向跟踪器的阻止。(blocking of Redirect Trackers)
什么是重定向跟踪器？
Firefox认真对待隐私提供了可以阻止重定向跟踪器(Redirect Trackers)的功能，以确保您不被跟踪和分析。在增强跟踪保护 2.(Enhanced Tracking Protection 2.) 0下可用，浏览器会清除此类 cookie，从而为用户清除状态。
Firefox 的ETP 1.0用于阻止跟踪器在第三方环境中使用 cookie。但是，它允许他们使用 cookie 作为第一方，因为这是网站所必需的。重定向跟踪器(Trackers)利用了这个缺陷。您可以称它们为中间网站，其唯一工作就是让浏览器感觉像是来自第一方。因此，当您单击应将您带到零售网站的链接时，它会暂时将您通过重定向，然后转到零售网站。这允许跟踪器作为第一方加载并允许存储 cookie。
现在发生的事情令人担忧。它可以访问其 cookie，这些 cookie 包含您来自何处以及您可能最终到达何处的所有信息。结果是，使用这种方法，您将很容易在互联网上被跟踪。阅读(Read more)有关 Firefox 公告的更多信息。

How to disable or enable Redirect Tracking Protection (ETP 2.0) in Firefox
Cybercriminals always come up with new ways of hijacking your sуstem. As such, a safe web browsing experience is necessary to avoid the compromise of your perѕоnal information. Browsers like Mozilla Firefox has developed a robust meсhanism to tackle this problem – Enhanced Tracking Protection. The newer version of it, ETP 2.0 protects you from an advanced tracking technique called Redirect Tracking Protection, also known as ‘Bounce Tracking‘. Let’s look at how to enable or disable blocking of Redirect Trackers in Enhanced Tracking Protection 2.0 in Firefox.
What is a Redirect Tracker?
Firefox being serious about privacy offers features that can block Redirect Trackers making sure you are not tracked and profiled. Available under Enhanced Tracking Protection 2.0, the browser clears such cookies, which cleans the state for the user.
Firefox’s ETP 1.0 is used to block trackers from using cookies in a third-party context. However, it allowed them to use cookies as first-party as it was necessary for the websites. Redirect Trackers took advantage of this flaw. You can call them an intermediate website whose sole job is to make the browser feel like it’s coming from first-party. So when you click on a link that should take you to a retail website, it instead momentarily pass you through a redirect, and then to the retail website. This allowed trackers to be loaded as first-party and were allowed to store cookies.
What happens now is the concern. It can access its cookies, which have all information from where you are coming and where you might end up. The result is that using this method, you will be easily tracked across the internet. Read more on the Firefox announcement.
