How to enable Sleeping Tabs in Microsoft Edge

In Microsoft Edge, the “Sleeping tabs” feature, also known as “Snooze tabs” is a useful feature designed to conserve system resources (such as memory and processor).

When you enable this “Sleeping tabs” feature, open tabs are put to sleep after inactivity to free up system resources and thus improve system performance and battery life. Then, the next time you go to the website, the tab will automatically resume.

It’s not a new idea, as similar features are already available in other browsers through extensions such as The Great Suspender for Chrome. However, Microsoft has built one into the Chromium version of Microsoft Edge, starting with version 88 and higher releases.

In this article, you will learn the steps to enable, configure and disable the Sleeping Tabs feature in the Chromium version of Microsoft Edge to reduce resource usage on Windows 10 or Windows 11.
