No matter how diligently you clear your cache and erase your history, web browsing leaves traces on your computer. If you need keep your browsing private, then an Ubuntu Live CD is the answer.

无论您多么努力地清除缓存并清除历史记录，Web浏览都会在您的计算机上留下痕迹。 如果您需要保持浏览私密，那么答案就是Ubuntu Live CD。

The key to this trick is that the Live CD environment runs completely in RAM, so things like your cache, cookies, and history don’t get saved to a persistent storage location. On a hard drive, even deleted files can be recovered, but once a computer is turned off the data stored in RAM is unrecoverable.

此技巧的关键是Live CD环境完全在RAM中运行，因此诸如缓存，Cookie和历史记录之类的内容不会保存到永久存储位置。 在硬盘驱动器，甚至删除的文件可以恢复，但是一旦计算机关闭时存储在RAM中的数据无法恢复。

In addition, since the Ubuntu Live CD environment is the same no matter what computer you use it on, there’s very little identifying information that a website can use to track you!

此外，由于Ubuntu Live CD环境无论在什么计算机上使用都相同，因此几乎没有识别信息可被网站用来跟踪您！

The first step is to either burn an Ubuntu Live CD, or prepare a non-persistent Ubuntu USB flash drive. Ubuntu treats non-persistent flash drives like CDs, so files will not be written to it, but if you’re paranoid, then using a physical CD ensures that nothing gets written to a storage device.

第一步是刻录Ubuntu Live CD，或者准备一个非持久的Ubuntu USB闪存驱动器。 Ubuntu将非永久性闪存驱动器像CD一样对待，因此不会将文件写入其中，但是如果您偏执，那么使用物理CD可以确保不会将任何内容写入存储设备。

Boot up from the CD or flash drive, and choose to Run Ubuntu from the CD or flash drive if prompted (for more detailed instructions on booting from a CD or USB drive, see this article, or our guide on booting from a flash drive even if your BIOS won’t let you).

从光盘或闪存驱动器启动，如果提示选择从CD或闪存驱动器运行Ubuntu的(从CD或USB驱动器上的引导的更多详细说明，请参阅这篇文章，或启动我们的导游从闪存驱动器，甚至如果您的BIOS不允许您)。

Once the graphical Ubuntu environment comes up, you can click on the Firefox icon at the top of the screen to start browsing.

与仅使用以隐私为中心的浏览器相比，这有点麻烦，但是如果您的浏览在硬盘上没有任何痕迹非常重要，那么最好使用Ubuntu Live CD。
