What Timer Alarm Stopwatch does

Timer Alarm Stopwatch is a browser add-on that lets you set a countdown timer, an alarm, or run a stopwatch without leaving your tabs. Its interface opens as a toolbar popup by default, but right-clicking the icon lets you switch to a new-tab view or a standalone window instead, depending on how you like to work.

How the interface is organized

The extension splits into three tabs on the left: Timer, Alarm, and Stopwatch. A button at the top of the interface adds a new timer or alarm, where you set the duration or trigger time. The Stopwatch tab keeps it simple with start, reset, and lap buttons for tracking elapsed time during a task.
