You can view a screencast by Mozilla developer Mike Beltzner, demonstrating some of the new features in Mozilla Firefox 3, which is due out very soon. Weighing in at under four minutes, the screencast gives a concise overview of why you should be excited about Firefox 3. Due to its visual nature, the screencast shows Firefox’s features far more clearly than the many written previews that have been published. A picture really is worth a thousand words.”
