Firefox is testing a feature that alerts users whenever they visit a website that has been hacked in the past. Firefox is working in collaboration with Troy Hunt, a security expert known for his data breach notification service 'Have I Been Pwned'.
Hunt himself confirmed the news via a Twitter post.
As many people have now worked out, yes, we're doing some awesome things with @mozilla and @haveibeenpwned 😎 https://t.co/UFW0CNLGtk

Hunt explained they were still working on how the implementation will play out. "Firefox is just looking at which sites have been breached and we're discussing other ways of using the data in the future," Hunt told Engadget. He further said, "They've got a broad reach and surfacing this info via Firefox is a great way to get more exposure around data breaches."
The feature is quite basic as of now. If you visit any site where Have I Been Pwned is implemented, it will give alerts, "You have visited a hacked website." It won't stop you from entering but it does give users an idea that, at some point or another, the site's security procedures were less than optimal.
The update is still in early stages, but you can download it from GitHub and then compile it and add on to Firefox.
