Mozilla has released the first beta of its Firefox 4 for Android and Maemo. The browser is based on the Firefox 4 core and should be released in the same time frame as the big brother.

The mobile browser, which is arguably the most advanced browser for smartphones available today, includes Firefox Sync, a cloud feature that enables users to sync browsing history, passwords, form-fill data and bookmarks, as well as open tabs.

There is also the Awesome Screen that is designed to minimize typing requirements on smartphones, as well as tabbed thumbnail browsing. There are even some performance-enhancing features such as Electrolysis, which increases performance by rendering the browser interface and content separately, as well as Layers, which Mozilla claims improve the performance of graphics-intensive tasks such as scrolling, zooming and animation.

Firefox 4 for Android/Maemo was previously known as Firefox 2.0 for Android & Maemo. Mozilla bumped the version up to 4.0 to avoid confusion about the two browsers as they are built on the same technology.
