This is so exciting. Last night Mozilla released Fennec -pre-alpha- for Android! Vladimir Vukićević posted a link to the latest build of Fennec for Android. You can download and test it here. (make sure you have checked the box that says “Unknown sources” in the settings first)
Keep in mind though that this release requires Android 2.0 or above. It has been tested only on Motorola Droid and the Nexus One. And there is high probability to cause your phone to crash or make it temporarily unresponsive. You can still test Fennec on you desktop if you want to.
There is an experimental version of Weave that is compatible with this build.
We’ve created a temporary Google Group for feedback about this pre-alpha build.
