great extensions, helps me with alarms

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.

This plugin is like democracy. Sometimes it works, sometimes it doesnt. Mostly it doesnt. Shame.

Doesn't do anything. When the timer gets to zero, no sound. When the alarm time passes, no sound. No animation, nothing. It will let me set up as many alarms and timers as I like but none of them make any sound. All the of the alarm options play for me when selecting the sounds, but when the timer/alarm is up, nothing happens.

Extremely light and easy to use!

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

all good, thanks (windows 10, firefox)
