Tor Browser 4.5 protects better against third-party tracking. Often when visiting a website, many connections are created to transfer both the content of the main website (its page, images, and so on) and third-party content from other websites (advertisements, Like buttons, and so on). In Tor Browser 4.5, all such content, from the main website as well as the third-party websites, goes through the same Tor circuits. And these circuits are not reused when visiting a different website. This prevents third-party websites from correlating your visits to different websites.
Tor Browser 4.5 now keeps using the same Tor circuit while you are visiting a website. This prevents the website from suddenly changing language, behavior, or logging you out.

The Amnesic Incognito Live System (Tails) 是基于 Debian 的自启动光盘或 USB 发行，其目标是为用户提供完整的因特网匿名功能。该发行装备了一些因特网应用程序，包括网页浏览 器、IRC 客户端、邮件 mail 客户端、即时消息信使，这都以安全为理念进行了预配置，并对网络流量进行了匿名性处理。为达到此目标，Incognito 使用了 Tor 网络，以使得网络流量很难被追踪。
