Microsoft recently rolled out the Vertical Tabs feature in the Edge browser, allow users to move tabs to the vertical list on the left side. The purpose is to make it easier for the users to manage tabs quickly and easily, especially when lots of tabs are open.
Starting with Microsoft Edge Canary v90.0.810.0, it is now possible for the users to adjust the width of the Vertical Tabs. With resizable vertical tabs, users can quickly expand the tabs to check more information about active web pages.
