Microsoft is testing a new feature called “Sleeping tabs” in Edge Canary


Understanding user expectations from a browser is what developers need to take care of. Google launched a feature named ‘Proactive Tab Freezing‘ in Chrome v79 that reduces the load on the browser. A similar yet advanced feature is on the ‘to-be-updated’ list of Edge named ‘Sleeping Tabs‘. This feature is currently been tested on Microsoft Edge Canary version 87.0.643.0.

After the update, if the feature is enabled, users do not have to worry of RAM been consumed in background from inactive tabs. The in-active tabs sleeps after a certain time and when clicked upon gets active again. This feature is been introduced to improve performance of browser and system when used extensively ahead by the user involved in several tasks at a time.

You can check out the Microsoft article explaining how the Sleeping Tabs feature will improve memory usage in Microsoft Edge
