One of the new features in firefox 4 is the ability to place the tabs either below or above the address bar. This tutorial will show you how to toggle between the two areas.
Oh, firefox. I would accept a purple browser and netscape’s user interface if you would just fix your memory leaks and crashes. Instead, I’m describing how to either move tabs above or below the address bar. If you just know where to right-click, it’s pretty simple.
1. Right-click (control-click for OS X) to the right of the address bar.
2. Click Tabs on Top if you want them on top
3. Unclick Tabs on Top if you don’t
Tabs on Top:
Tabs on Bottom:
