Browser security refers to the measures and features that protect users while they browse the internet. This includes safeguarding against threats like malware, phishing attacks, and data breaches. Modern web browsers, such as Google Chrome and Mozilla Firefox, incorporate security features like pop-up blockers, secure connections (HTTPS), and warnings about unsafe websites to enhance user safety. Additionally, browser security involves keeping software up to date to patch vulnerabilities. Users can also improve their security by using strong passwords, enabling two-factor authentication, and being cautious about the information they share online. These practices help create a safer browsing experience.
