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 Location 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! 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.

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 it's own set of controls.

This is however a personal preference and you can change it back and forth as you like.
