I will love you for ever and ever if you post the Firefox theme. =D
It took me a little while to figure how I actually made the theme, since I cobbled it all together without writing down what I did
Anyway, got it figured out here are the steps:
Goto Tools -> Option -> Tabs, then check the "Always show the tab bar" option.
Install the Chromifox Theme
Install the Stylish Extension
Install the Locationbar
