I only installed this for one purpose and one purpose only, and it doesn't really work: One-click blocking. It works a fraction of the time, but a huge portion of them pop up a confirmation box explaining they can no longer see your posts, etc.

Very mediocre experience so far

2025／05／21現在、数ヶ月前からPC（Win10）のFEP（MS-IME、ATOK両方）の挙動がおかしくなり、このアドオンをオンオフすると回復する、という謎現象に悩まされております。このアドオン、便利は便利なので削除する気にもなれず、かといってこのまま放置する訳にもいかずで、どうしたものか･･･

It doesn't really work on FF 80.0.1 for Ubuntu. There's no retweets timeline and I'm not sure about the chronological timeline. Stuff that should be hidden (bookmarks and such) is not.
