All in one extension to manage your schedules. You can define multiple alarms, use the stopwatch with as many "lap"s as required or simply use the timer with pause and resume support.

This extension uses the built-in API to set alarms hence the extension works even if the UI is hidden or your browser gets restarted. This extension offers alarm sound snoozing which snoozes the alarm sound 3 times with 5-minute delay.

The extension displays a high-priority desktop notification when either an alarm or a timer is fired, also it plays two different sounds to get the user-attention.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Alarm, Timer and Stopwatch does not require any sensitive permissions.

Risk impact analysis details
    Risk likelihood
    Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

    Alarm, Timer and Stopwatch has earned a fairly good reputation and likely can be trusted.
