thanks its very useful extension

The alarm window notifying about timer ran out, should not disappear automatically, but only after user click it. That would prevent missing the alarm when user is out of computer at alarm time.

Some feature request: can choose to mute (with no sound), or show notification only (not a new window).

Funcional e com design elegante. Bem legal a possibilidade de ter vários timers e ainda poder escolher qual musica tocará. Obrigado, Karl

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

great extensions, helps me with alarms

BUG: It doesnt trigger alarms consistently. I think the issue is if Firefox closes and the alarm happens later a day or so later, then it forgets. For example, i have two alarms set right now and i have had Firefox running for 8 hours now but prior to this my system was off...the timers were to trigger right now but both did not. Its a clear long time bug that the author doesnt care to fix.

AUTHOR: Please add a context-menu so one can create a timer. Seems silly that one has to rely on the icon to get access...i prefer to hide the icon because it just sits there doing nothing.

This add-on is really useful for me. However, I gave it only four stars because sometimes there is no sound.

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.

Great, easy to operate timer.
