Fennec, Mozilla's codeword for mobile Firefox builds, has just made its pre-alpha debut on Android. The tastefully named Vladimir Vukićević informs us that it's pretty much a debug release, with unoptimized memory utilization and some quirks rebooting the app when it's started and when add-ons are installed, but it is at a stage where the devs felt they could get useful feedback from a broader user base. It's not yet available on the Android Market, so you'll be needing to download it from the link below, and remember that you'll have to have an Android 2.0 or higher device, with OpenGL ES 2.0 capabilities also being recommended. If you've got all those boxes ticked, get downloading and come back to tell us how that WeaveSync is working out for you. We've got video of an older build running on a Nexus one after the break, just to whet some appetites.
