FUO is a free Chrome add-on developed by Camillo that brings a unique rating system to your Facebook experience. This add-on allows you to assign a symbol, called "judgment," to each user that appears on your Facebook feed.

Once connected to Facebook (consent will be requested the first time), every user on your feed will have two FUO symbols next to their name. The first symbol represents your own judgment. By hovering over it with your mouse, a window will appear where you can click and give your rating.

The second symbol represents the most frequent judgment received by the entire Facebook community. It provides an interesting insight into how users are perceived by others. With FUO, you can easily see the general opinion of a user without having to read through comments or posts.

FUO is a convenient tool for those who want to quickly assess the reputation of a Facebook user based on the collective judgment of the community. It adds a new dimension to your Facebook experience, allowing you to make informed decisions about engaging with different users.

With its simple and intuitive interface, FUO seamlessly integrates into your Facebook feed, providing valuable information at a glance. If you're looking for a way to enhance your Facebook experience and gain insights into user reputation, FUO is worth giving a try.
