Product summary
Review the store description, core capabilities, and common use cases.
An "Stopwatch, Timer and Alarm" add-on allows you to quickly create a timer, alarm, or change the stopwatch in your browser.
This add-on may be used in three different ways: as a toolbar button, in a new tab, or alone. Simply right-click on the toolbar button to pick your context. There are three tabs on the left side of the interface; please check each one to get more information. A button appears at the top of the interface to create a new timer or alarm. Select this button to modify timer settings or alarms. The start, reset, and lap buttons may be found on the stopwatch tab.
