Using a browser that blocks third-party trackers isn’t just important for privacy — it usually means it runs much faster, too. Most trackers are just scripts that run in the background on a number of websites. You can’t see them, but you can feel them slowing down your browser. As of version 67 of Firefox, fingerprinting and cryptominers are also blocked. If you’re not familiar with cryptominers, here’s an example of how they can affect you: maybe you’ve experienced your computer suddenly running hotter or the battery depleting faster than normal. That’s often the byproduct of cryptominers creeping around on your device.
浏览器能够阻止第三方跟踪器不仅对隐私很重要 — 通常也意味着可以运行得更快。大多数跟踪器只是一些网站后台运行的脚本。您看不到它们，但可以感觉到它们拖慢了浏览器的速度。从 Firefox 67 版本开始，数字指纹跟踪程序和加密货币挖矿程序也会被拦截。如果你不熟悉“挖矿”，这里有一个案例可以说明它们是如何影响您的：也许您经历过计算机突然升温变卡，或者电量消耗得比平时更快。这往往是“矿工”在您的设备上肆虐的“杰作”。
