Hi Firefox contains built-in Phishing and Malware Protection to help keep you safe online. These features will warn you when a page you visit has been reported as a deceptive site (sometimes called “phishing” pages), as a source of unwanted software or as an attack site designed to harm your computer. This feature also warns you if you download files that are detected as malware. More info [[How does built-in Phishing and Malware Protection work?]]
