How to Use Vertical Tabs in Microsoft Edge Mar 16, 2021, 8:00 am EDT | 2 min read With vertical tabs in Microsoft Edge, you can now view a convenient vertically-oriented list of tabs on the left side of your browser window. Here’s how to use the tab sidebar in Edge on Windows, macOS, or even Linux. How to Show and Hide the Vertical Tabs List Before we get started, make sure you’ve updated to the latest version of the Microsoft Edge. Vertical tabs were added in Microsoft Edge version 89, which was released on March 4, 2021. Next, launch Edge and open a new window.
