Firefox 4.0 mockups

Just a few days after showing us what Firefox 3.7 may have in store visual-wise, Mozilla have released some windows theme mock-ups of what version 4 of the open-source browser might look like.

Personally I would go for version B, mainly as it ties the location bar into a tab rather than just sitting on top like it currently does. (anyone else see some sort of Chrome insparation going on?)

Which version do you prefer? add your comments below…
