Mozilla said the goal in developing this alpha version of Fennec was to make improvements in the responsiveness and performance of the browser. In order to make those changes, Mozilla is working with two new technologies -- "Electrolysis" and "Layers." The first technology, Electrolysis, makes it into the alpha, while the second, Layers, won't be added until Fennec hits beta.
Layers will be worked into the next version, and once it is added users should notice significant performance in navigation actions such as scrolling, zooming, animations, and video. Mozilla hopes to batch Layers with hardware-accelerated graphics engines found in today's mobile phones.
Mozilla's vision for mobile browsing includes seamless transitions between desktop browsing sessions and mobile browsing sessions. Fennec supports add-ons and Firefox Sync, which transports the Awesome Bar, open tabs, bookmarks, and passwords from the desktop to the mobile device.
Until then, the Alpha version of Fennec is a start for wider acceptance of Firefox mobile. It has some serious competition to worry about. The native Android browser is very good, and there are already alternatives for Android handsets from the likes of Dolphin and Opera.
The fact that the browser is being labeled an "alpha" means that it is far from complete, and may be buggy. Install and use at your own risk. Mozilla said that it welcomes user feedback.
