Do you ever receive an email with a link and aren’t sure where it actually leads? It could be a fraudulent website trying to steal your login credentials or other sensitive information. And it’s not just emails—scam websites can appear even during regular web browsing. TrafficLight is a free browser extension that warns you about suspicious or fraudulent websites before you even open them. In this guide, we’ll show you how to add it to your browser and how it works in practice.

How does it work?

Before a webpage loads, it checks whether the site contains malware or phishing.

In search results, it displays icons: = safe, = dangerous.

TrafficLight is not an antivirus and won’t protect against malware in attachments.
