  • Reported Unwanted Software Page: This warns that the site may distribute unwanted software or programs that negatively impact your computer.
  • Reported Attack Page: This alerts you that the site may contain malware or other malicious code that can harm your device.

These measures help keep Firefox users safe from:

  • Phishing: Websites designed to mimic legitimate sites to steal credentials.
  • Malware: Software intended to damage or disable computers and computer systems.
  • Unwanted Software: Programs that may be bundled with other software or installed without explicit consent.

Firefox uses regularly updated lists of unsafe websites to identify and block these threats. This ensures that users are protected from the latest online dangers.
