usefull! But when i enter a number, I can't use the numpad or the mouse wheel. Is it normal? To enter 25, i need to click 25 times on the arrow. It seems too much!

This is good but i think i could be a lot smaller and have more than 4 timers saved

minimum time a minute

1. периодически не дает нажать кнопку сохранить, приходиться переоткрывать настройки
2. нет визуальной части о том сколько времени осталось до конца

I really want to like this timer but it doesn't always alert me when time is up. It's a little frustrating because when it does alert me, it changes my desktop display to a blank white screen.

However, I really enjoy having multiple timers to set and being able to customize. But due to the inconsistency in alerts, I've had to remove from Firefox Developer.

Good addon but now have some bugs on my browser. Alarms not work. Firefox 67.0.2
