Firefox 4 beta 3 brings multi-touch to Windows 7

Mozilla have released Firefox 4 beta 3 adding features such as multi-touch support for Windows 7 systems. The release comes less than a month after the release of beta 2. The multi-touch implementation allows developers to write web applications which can respond to touch gestures for scaling, rotation and other manipulations. The feature is demonstrated in a blog posting.

Beyond the multi-touch support, the two other major features of this release are its availability in 34 languages and an optimisation to the handling of numeric values in JavaScript, which improves performance for computation heavy web applications.

More details about the release, including a list of known issues, can be found in the release notes and in the official release announcement by Beltzner. Firefox 4.0 Beta 3 is available to download for Windows, Mac OS X and Linux. Alternatively, Firefox 4.0 Beta 2 users can upgrade to the new version, either by waiting for the automated update notification or by manually selecting "Check for updates" from the Help Menu.

Firefox binaries are released under the Mozilla Firefox End-User Software License Agreement and the source code is released under disjunctive tri-licensing that includes the Mozilla Public Licence, GPLv2 and LGPLv2.1. The latest stable release of Firefox is version 3.6.8 from the 23rd of July.
