How does clearing browsing history contribute to online safety?

Clearing browsing history significantly contributes to online safety by helping to prevent tracking of online activities. When you clear your browsing history, you remove records of the websites you've visited, along with cookies and cached files that can be used to profile your online behavior. These profiles can be utilized by advertisers, data brokers, or even malicious entities to monitor your browsing habits and target you with ads or other unwanted content. By regularly clearing your history, you reduce the amount of personal data that can be harvested, thereby enhancing your privacy and protecting against identity theft or targeted phishing attacks.

The other options mention benefits that can occur from managing browser data but are not directly related to online safety in the same way. For example, while clearing browsing history may lead to faster performance or an improved experience, this is not primarily focused on safeguarding user activity. Similarly, it does not enhance the computer's performance to the extent that it relates to online security, nor does it automatically delete phishing emails, which requires separate security measures.
