If you're interested in making more changes to the user interface, please see How to make the new Firefox look like the old Firefox.

If you have updated from an older version of Firefox, you may notice that the tabs are now on top of the navigation toolbar. You can move these tabs back below the navigation toolbar if you'd like.

How do I put tabs back on bottom like they used to be?

  1. In the address bar, type about:config and press EnterReturn.

    • The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!I accept the risk! to continue to the about:config page.
  2. In the Search field box at the top, type browser.tabs.onTop.
  3. Double-click the browser.tabs.onTop preference to set its value to false.
  1. Open the Tabs On Bottom add-on page.
  2. Click the green Add to Firefox button to install it.
  3. Firefox will download the add-on and ask you to confirm that you want to install it.

Why was this change made?

The main reason is that it just makes more sense. With tabs underneath, the tab and the controls were grouped together and the page was separate. With tabs on top they are now all grouped together so that each tab has its own set of controls.

This is however a personal preference and you can change it back and forth as you like. The hidden preference that was available in previous versions was removed because it caused problems with the new user interface.
