Microsoft Edge gets the “Sleeping tabs” feature

    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‘. The company has added this feature to Microsoft Edge v88.0.705.50.

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