Beta 5 of Firefox 4 for Mobile available
The Mozilla foundation has announced the availability of the fifth beta for Firefox 4 for Mobile, for phones running Android (v. 2.0 or higher), and for Maemo on the Nokia N900. It can also be installed on a PC, although such a desktop version is for development purposes only and will not have full functionality. This release requires a phone with an ARMv7 processor. Users are recommended to visit the Platforms and Device Requirements page before downloading.
The release notes state that this release contains no major new features but that development has focussed on "making the browser faster, more stable, and more usable". Performance has been improved, notably for start-up and page load speed, and both memory and CPU usage have been optimised. There have also been many bug fixes and usability improvements. A blog post by Mozilla developer Mark Finkle shows some graphs of performance tests.
Beta 5 is available to download to a PC or alternatively, from a phone a user can visit Firefox.com/m. The source code is released under the disjunctive tri-licence that includes the Mozilla Public Licence, GPLv2 and LGPLv2.1.
