Fennec ‘s not out anytime soon yet, but it looks like they’re testing the full Firefox interface on Android at the moment, not any mobile version – but the real deal.
“You'll note that this is the full Firefox interface, and not the Fennec/Firefox Mobile UI; we're testing with the full interface because it's significantly more complex than the mobile UI and stresses Gecko much more. So, if the full UI works, then Fennec should work fine as well. Given the interest in Android on netbook and tablet devices, an updated version of the full Firefox UI might find a home on some of these.”
Developer Vlad states that keyboard entry doesn’t quite work yet, and the browser isn’t ready for heavy-duty work yet, but that Android has been pretty great to work with so far. No alpha release yet, but they’re getting closer and closer.
