TSE - Torrents Search Engine is a subscription-based search engine designed for Firefox that allows users to efficiently search across multiple torrent trackers. It operates solely on vanilla JavaScript and supports popular trackers including Rutracker, Rutor, and Kinozal. The application features simultaneous searches, Google suggestions for queries, and a custom tracker editor in beta. Users can also enjoy a dark theme and a user-friendly interface that simplifies navigation.

The program offers advanced functionalities such as result filtering by tracker, sorting options, and direct .torrent downloads, although functionality may vary by tracker. A unique TopSeeds mode enables users to prioritize results based on the number of seeders rather than recency, enhancing the chances of finding well-seeded torrents. The reset button allows for easy removal of all settings, making it adaptable to user preferences.
