Welcome

Simple Timer is a Firefox/Thunderbird extension that operates as a clock or a timer. Information can be displayed in your toolbar, as well as in an informative toolbar tooltip.

Clock mode displays the time and/or date in a format that is highly customizable.

Timer mode has three functions:
1. Count up from zero.
2. Count down from any time (less than 24 hours). You can set as many timers as you want.
3. Select a specific time of the day to receive a notification. You can also specify the day (daily, weekdays, weekends or a specific day). You can set as many notifications as you want.

Completed timers can be recorded in an event log
.
Visual and audio alarms can be set to trigger when the timer has completed.

Use the sidebar to the left for more detailed information. I hope you find this extension useful!
