This extension was built for the purpose of providing a different way of browsing Twitter. The idea behind this extension is simple; we make it impossible for users to scroll through the same tweets multiple times. It is a basic concept and works by recording the last messages that a user has viewed, and dimming them the next time that the user visits Twitter. This way, we allow users to browse through Twitter without the fear that they will not be able to differentiate between the unread tweets and new updates.
