This tutorial will show you how to add and remove sites on an exclude list to the never put these sites to sleep 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.
To help you stay on task and limit potential compatibility issues, the following activities prevent sites from going to sleep:
- The page is currently visible (active tab)
- The page is currently holding a Web Lock or an IndexedDB transaction
- The page is sharing its BrowsingInstance with another page
- The page is your company’s internal (intranet) site
- The page is currently being inspected by DevTools
- The page is currently playing audio
- The page is currently capturing a window or screen
- The page is currently capturing user media (webcam, microphone, etc)
- The page is currently being mirrored (casting, etc)
- The page is on the user’s block list in Settings
- The page is currently using WebUSB
If you like, you can add sites you never want put to sleep in Microsoft Edge to an exclude list. Adding a site to the exclude list will prevent it from sleeping from the Sleeping tabs and Efficiency mode features.
