Browsers and Mail Change Inactivity Timeout for Sleeping Tabs in Microsoft Edge

This tutorial will show you how to change the background tab inactivity timeout for sleeping tabs in Microsoft Edge for your account or all users in Windows 10 and Windows 11.

The Microsoft Edge web browser is based on Chromium and was released on January 15, 2020. It is compatible with all supported versions of Windows, and macOS. With speed, performance, best in class compatibility for websites and extensions, and built-in privacy and security features.

The sleeping tabs feature in Microsoft Edge makes background tabs sleep after two hours of inactivity by default in order to free up resources for active tabs, new tabs, and other applications on your device. Sleeping tabs will fade to indicate they’ve released resources. To resume a sleeping tab, click/tap on it like a normal tab. The tab will un-fade and your content will be immediately available.

When efficiency mode is turned on and active, the Put inactive tabs to sleep after the specified amount of time setting will always get set to 5 minutes of inactivity and grayed out. To set the amount of time using the sleeping tabs settings, turn off efficiency mode.







1 Open Microsoft Edge.

2 Click/tap on the Settings and more (3 dots) button, and click/tap on Settings. (see screenshot below)


3 Click/tap on System and performance in the left pane. (see screenshots below step 4)

4 Select an inactivity time you want in the Put inactive tabs to sleep after the specified amount of time drop menu. (see screenshot below)

2 hours of inactivity is the default setting.
