Windows 7 - Firefox 3.7 Alpha 4 Next - Gecko 1.9.3 Alpha 4.

Mozilla is currently cooking a new Alpha development milestone of Firefox 3.7, the label it is using for the very early builds of the next iteration of its open source browser. In fact, as it was the case with the previous Alpha release of Firefox 3.7, early adopters will in fact be getting a new Build of the Mozilla Developer Preview of Gecko 1.9.3. So far, developers have already received no less than three Alpha releases of Firefox vNext, and it looks like the first Beta is still far in the distance.
