Which browser feature helps improve security by preventing tracking?

Incognito mode is specifically designed to enhance user privacy and security while browsing the internet. When a user activates incognito mode, the browser does not save the browsing history, cookies, or site data. As a result, this feature helps prevent tracking, as websites are unable to store tracking cookies on the user's device during an incognito session.

Additionally, sessions in incognito mode are isolated from the regular browsing environment, meaning that any activity is not linked to the user's saved profiles or accounts. This feature is particularly useful for users who want to ensure that their online activities remain private, minimizing the trail left behind that could be used for tracking purposes.

Other options, like bookmarking or history management, are primarily focused on saving and managing browsing sessions rather than enhancing security or privacy. Extensions can help improve security and privacy as well but depend on the specific functionality they offer and may require additional user configuration.
