How to enable Vertical tabs in Firefox

Today I Learned that you can use Vertical tabs in Firefox since version 136.

To enable it, go to Menu > Settings > General > Browser Layout > Select: Vertical tabs.

In the sidebar, you can click on ‘Customize Sidebar’ for more options. I found the ‘Move Sidebar to the Right’ feature helpful for avoiding distractions. I’m still figuring out whether ‘Expand Sidebar on Hover’ is useful or not.
