If you ask me, that seems like 3.0 beta 1, as then the home buton also was up there. after that, it got moved to where it is in 3.0.. However, I might be wrong. Can't wait until it actually gets released.
EDIT: I did some research and there actually is a firefox 4 beta
from
http://news.cnet.com/think-firefox-3-is-fast-try-firefox-minefield/A colleague today showed me a cool, new browser that he's been using to browse the web at blisteringly fast speeds. The browser? Minefield. The author of the code?
Mozilla.
Yes, that same Mozilla that makes the Firefox browser. Minefield is, in fact, a way to glimpse into the future of Firefox, as it's a pre-release/alpha version of the Firefox browser.
After spending some time with Minefield, one thing is clear: the future of Firefox is fast. Lightning fast.
How fast? Some claim that it has the fastest javascript engine on the planet, which means it leaves Google's Chrome browser in the dust. In my own unscientific tests, I'd say that this assertion is correct. Ars Technica pegs Minefield as 10 percent faster than Chrome.
can't wait
I don't see though, Why they moved the home button back again...
