How do I get vertical tabs in Chrome?
Google Chrome doesn't support vertical tabs natively, so you'll need the help of a third-party extension. The perfectly named Vertical Tabs is the best option we found and it won't cost you anything. Simply download the add-on and then click the orange Vertical Tabs icon in the Chrome toolbar to activate it.
Why can't I turn on vertical tabs?
Perhaps you've hidden the button. Click Options (the three vertical dots at the top right), then Settings, then Appearance. The switch to display the vertical tabs button should be there.
