If you don’t want your online behavior used for ads, you can send websites a polite “thanks but no thanks” letter by checking the <a href="{ $url }">Do Not Track</a> option of { -brand-name-firefox }. Participation is voluntary, but the websites that participate will stop tracking you immediately.
若您不希望您的在线行为用于广告，可以勾选 { -brand-name-firefox } 的<a href="{ $url }">请勿跟踪</a>选项来礼貌地告诉网站：“谢了，请不要跟踪我”。虽然是否有效视网站而定，但同意该机制的网站会立刻停止跟踪您。
