Lifehacker shown a screenshot of the new Firefox 4.0 pre-beta for Windows. Here it is (Mozilla names Firefox beta versions “Minefield”):
Nice, isn’t it? So, I downloaded the new beta for Linux, and it looks like the screenshot below. I had to set the tabs to be on top; Windows version brings this for default (at least the one that I installed using Wine).
