This post shows students and new users steps to turn on or off fade sleeping tabs when using the Microsoft Edge browser.
A new feature added to Edge is its Efficiency mode, which is designed to help extend battery life by minimizing power usage and reducing resource usage (CPU usage) by modifying specific tab activity on tabs you’re not interacting with and putting inactive background tabs to sleep after 5 minutes or less.
The sleeping tabs feature in Microsoft Edge makes background tabs sleep after two hours of inactivity 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 on it like a normal tab. The tab will un-fade, and your content will be immediately available.
The steps below will show you if you want to turn off the fading and unfading of sleeping tabs in Edge.
