Mozilla Firefox 3.7 pre-alpha dubbed “Minefield” is out with some really great UI enhancements and an extensive use of Windows Vista/7 glass. In fact it seems like they’ve turned every portion of the UI into glass and this is really awesome. It’s still pre-alpha release but it gives you an idea of how Firefox 3.7 will look like.

There are no crashes yet and it works just fine except a small change I noticed: Every new tab seems to be opening like a process instead of a thread, that’s the reason why you can preview all your open tabs on the Windows Vista/7 taskbar.

Anyways, here are some quick screenshots of Firefox 3.7 pre-alpha.

First, the glassy tabs bar:

And here is the open tabs preview on my Windows 7 taskbar:

And here’s how the new Firefox 3.7 pre-alpha looks like. Awesome:
