Firefox 4.0 layout looks like Google Chrome(gallery)

Mozilla last week unveiled several prototypes of the more recent FireFox 3.7 layout, in which the browser's name column is removed and replaced with two drop-down menu keys on the right, just like Chrome debuted in early September 2008. The FireFox 4.0 design prototype has two options, one similar to the 3.7 concept and the other closer to Chrome's direction.
