How to Put Tabs Back on Bottom in Mozilla Firefox 4.0 at 6:13 AM

Mozilla Firefox 4.0 comes with Tabs on Top by default which might become quite difficult and annoying for some Firefox users who were used to bottom tabs. In this tutorial, i'll tell you how to put Tabs back on bottom as you used to get in older versions.
1. Open Mozilla Firefox, right-click on Toolbar and deselect "Tabs on Top" option.

2. That's it. As soon as you uncheck the option, it'll put the Tab bar on bottom.

It also enables Aero glass in Toolbar which looks good.
