While Mozilla's Fennec mobile Web browser isn't yet available for Windows Mobile but for the Maemo platform only (which is the preferred development platform), the Fennec developers made some good progress and recently released Fennec Alpha 2. While it's still an early developer release of the mobile version of Firefox, for testing purposes only, the initial focus of development was on building a new user interface that reflects Firefox's design principles and adds touch screen support and other features that are appropriate for mobile phones and other handheld devices.

For Alpha 2, the developers focused mainly on performance, improving the responsiveness of panning and zooming, both while pages are loading and when they have completed loading. Nevertheless, there are still many improvements which are intend to make, including enabling TraceMonkey by default.

However, the most important part is, that Mozilla still plans to release a first public Windows Mobile (Professional) build in late 2008 with the final release in 2009. At least that's what the milestones Wiki still claims.

If you don't want to wait for the first Windows Mobile release but want to test Fennec already, there are PC versions available for Windows, Mac and Linux.
