The first beta of Firefox 4 for Mobile is now available publicly as a free download. This release aims to increase performance and responsiveness using the two big architectures – Electrolysis and Layers.

This release delivers a rich set of features, including pinch-to-zoom, which is now supported on multitouch-capable devices, and the Awesome Screen, which instantly gives you access to your recent history, bookmarks and tabs just by tapping in the Awesome Bar.
