Nearly all major browsers have a private browsing setting. These exist to hide the browsing history from other users on the same computer. Many people think that private browsing or incognito mode will hide both their identity and browsing history from internet service providers, governments and advertisers. They don’t.

幾乎所有主要的瀏覽器都有隱私瀏覽設定。這些設定是為了對同一台電腦上的其他使用者隱藏瀏覽紀錄。很多人以為隱私瀏覽模式或無痕模式可隱藏自己的身分與上網紀錄不讓電信業者、政府、廣告商知道。然而這些設定只會清除系統上的歷史紀錄，方便您在公共電腦中處理敏感的個人資訊。 { -brand-name-firefox } 的功能不僅僅如此。
