Keep a lot of tabs open? Try our new vertical tabs layout to quickly scan
your list of tabs. With vertical tabs, your open and pinned tabs appear in
the sidebar instead of along the top of the browser. To turn on vertical
tabs, right-click on the toolbar near the top of the browser and select Turn
on Vertical Tabs. If you’ve enabled the updated sidebar, you can also go to
Customize sidebar and check Vertical tabs. Early testers report feeling more
organized after using vertical tabs for a few days.
