If you have a lot of tabs open in your web browser, you might find that you have one website or web app which misbehaves, consumes too much memory or processor time, or that crashes completely. You can view what’s going on with your browser tabs in Microsoft Edge by clicking the Menu icon (⋯) in the top right corner of the browser window, and from the menu that opens, clicking More tools, followed by Browser task manager.
This opens a window that displays all the different tabs, apps, and processes running in your browser, including web apps you might have pinned to the Start Menu. If you need to close a hung or misbehaving process, click it to highlight it and then click the End process button in the bottom right corner of the window.
Microsoft Edge makes it really easy to manage browser processes, web apps, and websites. You can download Microsoft’s Edge browser from HERE.
