Our automated build machines have just started producing pre-alpha Fennec for Android builds with the latest changes from developers each night. We have similar builds for the desktop version of Firefox and for the N900 to let testers have a way of getting the latest changes to provide feedback and report bugs. There are many changes that go in to each build, causing quality to vary some from day to day, but we’re always working to improve and stabilize the builds.
As of today the builds are still pre-alpha quality, but they’ll continue to improve over time. There are many exciting changes being actively worked on that will be showing up in the coming weeks. We are keeping this page up-to-date with some of the larger known issues and what phones Fennec is currently known to run on, which will change over time. We currently only run on Android 2.0 and above, and some bugs could cause your phone to stop responding, requiring a reboot. If you have installed our earlier build, you will need to uninstall it before this one will install due to a change in the way the builds are signed. These builds do not auto-update yet, so you’ll have to manually grab a new build when you want to see the newest changes.
Since the post Vlad made a few weeks ago about our first pre-alpha Android build, we have made lots of improvements based on the feedback we’ve received. We really value this feedback and look forward to more of it on these builds.
