Have you checked out Microsoft Edge’s Vertical Tabs feature? Normally, tabs display at the top of the browser like this.

But, if you’d prefer a cleaner look at the top of the page, you can switch your open tabs to the side. Just right-click and choose Turn on vertical tabs from the drop-down menu.

Or click the icon at the top far-left.

Your tabs will now appear on the side.

To switch back, just right click and choose Turn off vertical tabs.

That’s So Cool, having the Tabs on the side…..
I’m telling you, Microsoft Edge is going to become Every ones Browser here one of these Days!
