What web browser feature would be useful when using public computers?

A useful web browser feature for public computers is "incognito" or "private browsing" mode. This feature prevents the browser from saving history, cookies, and cached data, ensuring that no personal information is stored after the session ends. Additionally, it helps protect user privacy by minimizing the risk of sensitive data being accessed by the next user. Using this mode can enhance security when accessing personal accounts or sensitive information on a shared device.
