About this extension
This extension (1) indicates a website's accuracy and bias when applicable with a small badge on the Stopaganda icon in the extensions bar (with more detail when clicked), and (2) adds text decorations to Google, DuckDuckGo, Twitter, Facebook, and Reddit's r/news, r/inthenews, r/worldnews, r/canada, r/unitedkingdom, r/europe, and r/politics subreddits (as well as r/all and the front page with posts originating in the above subreddits) with accuracy and bias metrics (based on Media Bias/Fact Check's publicly available data). These data can be found by clicking on an article or post's decals or directly at https://mediabiasfactcheck.com/. Note that bias classifications are relative to general U.S. politics.
