The Official Media BiasFact Check Extension for Firefox is designed to enhance users' awareness of media bias while browsing social media platforms like Facebook. This subscription-based extension provides access to a comprehensive database of over 3000 media sources, offering users insights into the reliability of news articles and sources they encounter. It aims to combat misinformation and promote a more informed social media experience by highlighting potential biases in the news feeds.

The extension features an updated interface compatible with the new Facebook layout, introducing a collapsible news section that allows users to manage their feed more effectively. By clicking on the 'Collapse' section, users can select specific news categories to hide, ultimately reducing information overload and stress caused by contentious posts from friends. This tool is a valuable asset for those seeking a more curated and less stressful social media experience.
