Mozilla mobile team has just announced the availability of Fennec Alpha 3 for Windows Mobile. There are lot of new features and fixes, including improved start time, panning, compositor work, and support for a wider range of screen resolutions.
The first thing you’ll notice is the improved start up time. The next thing to notice is the much improved panning. Mozilla have implemented a tile cache rendering system (much like you see on Google maps) that allows us to cache previously rendered content and avoid duplicating the work. This allowed to switch over to native scrolling surfaces which has greatly improved panning performance
