Many a times hundreds of tabs are open in my browser window and I accidentally press a button on top left-hand corner which I have encircled in the screenshot below. I want to know is there a shortcut to open all those tabs in a single click or a key combination which have been accidentally closed by pressing this button. The browser I am using is Microsoft Edge 44.18362.449.0. The button with an arrow to left side in the screenshot is one which I am referring to.
The button doesn't close all the tabs, it sets them aside instead.
This is where your tabs go.
Just click the Restore tabs option and your tabs will be back.
