User Reviews

one of the best json formatter available for firefox, all others are outdated, old and unorganized ui and layout, but this one is a masterpiece i must say, it has modern ui, all features and other developer tools and clear instructions how to setup and make it work on firefox, because other addons, users dont know how to make it work on firefox as firefox natively use its own json viewer, this has all the features, great work
