Sophia Harvey (ID: 00000064edfec8b8) Voted 4 ★ - Updated 10/27/2023 works when it wants! sometimes it gets frozen and you have to delete it and re download it. It is the only one that works that I've tried.

Ian James (ID: 0000002b592a3f74) Voted 5 ★ - Updated 09/21/2023 Works wonderfully. I use this timer for ambient youtube videos or as a timer on podcasts. You do have to reinstall it if you cancel it or exit out of the tab it is timing. Still, it works as intended and is far better than similar extensions. I am a fan.
