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 when sleeping tabs is enabled. 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.

If you do not see a left pane, then either click/tap on the 3 bars menu button towards the top left OR widen the horizontal borders of the Microsoft Edge window until you do.

The Fade sleeping tabs setting will be grayed out if Save resources with sleeping tabs is not turned on.
