Twifiner is a Chrome add-on that aims to improve your Twitter experience by eliminating ads, reducing clutter, and offering additional functionalities. Features include simplified word muting, displaying original URLs instead of t.co links, showing account age, and more.

In the latest version 4 update, Twifiner now highlights message requests on the Messages page for better visibility, hides retweets on user profiles and the timeline, and offers the option to hide "Discover More". Several bug fixes were implemented, such as resolving issues with number display in tweets and notification count reset. The update also focused on enhancing performance by removing unnecessary features and permissions.
