Firefox has several security features to protect its users:

1. Web Security: Firefox uses HTTPS for secure connections. It also blocks content from websites that are known to be malicious.
2. Phishing Protection: Firefox warns users when they are visiting a suspicious website that might be trying to steal their personal information.
3. Pop-up Blocking: Firefox prevents pop-ups from the websites that are known to be malicious.
4. Password Manager: Firefox remembers the passwords of the user, but the passwords are encrypted with a master password, which the user has to provide every time they access the saved passwords.
5. Private Browsing: Firefox offers a private browsing mode, which doesn't store browsing history, cookies, and other data.
6. Extension Security: Firefox extensions go through a review process before being available to users, ensuring that they are safe and secure.
7. Anti-Tracking: Firefox blocks third-party tracking cookies, which helps to prevent websites from collecting user data.
