    How to Enable or Disable Sleeping Tabs in Microsoft Edge Chromium


    Microsoft has adopted the Chromium open source project in the development of Microsoft Edge on the desktop to create better web compatibility. This new Microsoft Edge runs on the same Chromium web engine as the Google Chrome browser, offering you best in class web compatibility and performance.

    The new Chromium based Microsoft Edge is supported on all versions of Windows 7, Windows 8.1, Windows 10, Windows Server (2016 and above), Windows Server (2008 R2 to 2012 R2), and macOS.

    To improve memory and CPU utilization of the Microsoft Edge browser, Microsoft has developed a feature called sleeping tabs.

    Early internal testing of devices with sleeping tabs has shown a median memory usage reduction of 26% for Microsoft Edge. Microsoft's internal testing has also shown that a normal background tab uses 29% more CPU for Microsoft Edge than a sleeping tab. These resource savings should result in excellent battery savings. Although individual device performance varies depending on configuration and usage, Microsoft expects the decrease in resource and battery usage to create a better browsing experience for users.

    Sleeping tabs builds upon the core of Chromium’s “freezing” technology. Freezing pauses a tab’s script timers to minimize resource usage. A sleeping tab resumes automatically when clicked, which is different than discarded tabs, which require the page to fully be reloaded.

    Microsoft built upon the freezing technology to create sleeping tabs. This feature allows inactive background tabs to “go to sleep,” releasing system resources after a set amount of time. These resources include both memory and CPU and can be used for new or existing tabs or other applications running on your device.

    By default, Microsoft set tabs to go to sleep after two hours of inactivity. If two hours isn’t right for you, you can choose a different time interval. Tabs that are asleep will fade to let you know 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 there immediately. You can also add sites you never want to sleep to a block list in Settings.

    This tutorial will show you how to enable or disable sleeping tabs in the Chromium based Microsoft Edge.

    With this technology, it is possible that some sites may not work as expected after they go to sleep. Microsoft has built heuristics to detect these scenarios and prevent those tabs from sleeping to keep you in your flow. Microsoft is eager to get your feedback on sleeping tabs. If you experience a compat issue, please refresh the page and let Microsoft know through Microsoft Edge by pressing Shift+Alt+I on a Windows device or going to Settings and more … > Help and feedback > Send feedback.


    For a better control of discarded tabs you can open edge://discards/

    Are sleeping tabs feature with Edge (or Chrome for that matter) compatible with extensions like The Great Suspender or should the sleeping tabs feature not be enabled if 3rd party tab suspend/freeze/sleep extensions are used?

    Note: I am familiar with the privacy issues for the newest version of The Great Suspender and use the older 7.1.6 version before the extension was sold.

    Hello @bamajon1974,

    The Sleeping Tabs feature is only applied to tabs opened in Microsoft Edge. It will not apply to an extension.

    @Brink

    I meant...does the Sleeping Tabs feature interfere with The Great Suspender since both are used to hibernate tabs?

    It's possible since they do control the same thing, but it's something that will have to be tested to see.

    Hello hamid3pnn,

    The Save resources with sleeping tabs setting would only be available if enabled using option 1 first.
