Firefox 3rd Party Installer Campaign

July 14, 2024
In 2023, a significant portion of Firefox downloads came from unknown sources. We believe many of them came from 3rd party websites that let you download Firefox. While some websites are okay, others can put you at risk of downloading an old version or a build with the wrong locale, leading to security risks, a bad user experience, or even malicious installations.
Help us uncover the mystery behind these 3rd party websites that offer Firefox installer by participating in this campaign!
