The main feature that this beta version has brought is, as I said earlier, the speed improvements across the board. Also, this release is the fastest performing Firefox 4 beta for mobile so far. Apart from faster start-up , page-load times, it has responsiveness to panning and zooming. Also, Firefox 4 beta for Android offers more than 100 Firefox add-ons to customize the features, functionality and look of your Web experience.
Other advancements in this release include increasing stability, reducing installation memory usage, improving readability with zooming, and fixing some keyboard issues. The latest beta is available to download from the Android Market and if you use a Nokia N900, visit this link to get downloading.
