Block deceptive content and dangerous downloads in Firefox

Websites you or your children visit may sometimes try to download and install malicious software on your computer without your approval. Firefox warns you of these attacks so you can take action against them and block suspicious content before it’s downloaded to your disk. To make sure this protection is enabled visit your Security settings:

  1. Click the menu button.
  2. Click Settings.
  3. Go to the Privacy & Security panel.
  4. Scroll down to Security.
  5. Under Deceptive Content and Dangerous Software Protection, make sure the following boxes are checked:
  • Block dangerous and deceptive content
  • Block dangerous downloads
  • Warn you about unwanted and uncommon software

When Firefox detects you've entered a suspicious site, it will display a warning in the address bar. If an unwanted, potentially harmful download is detected, a warning message will display in the Downloads panel and Firefox will block the download.
