Tab Countdown Timer

A Chromium Extension that allows you to set a timer that counts down and then closes the tab.

Tab Countdown Timer is a Chromium extension that lets you easily set countdown timers on individual tabs. Once the timer reaches zero, the tab automatically closes, helping you manage your browsing sessions efficiently. Each tab can have its own unique timer, and you can set the time by typing or using the mouse wheel. The extension supports dark mode based on your system settings and remembers your last timer values for convenience.

Recent updates improved styling, error handling, and compliance with Chrome Manifest V3 standards, delivering a smoother, more reliable experience. Whether you want to limit time spent on certain tabs or manage multiple countdowns, Tab Countdown Timer provides an intuitive and customizable solution.

Works very well. The tab doesn't have to be active, it even works when I lock my screen on windows 10. Couldn't ask for better. Thank you!

А можно добавить возможность вводить ещё и секунды? Если нужно закрыть вкладку с точностью до секунды, а минимум только минута,это придётся ждать ещё целую минуту. Расширение отличное, но этого не хватает.

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.

Tab Countdown Timer does not require any sensitive permissions.

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 Chrome extension.
