Originally Firefox 3 was due to be made available by November 2007. Although we're still only in beta, the browser shows a lot of promise and is expected to be feature-complete by beta 5, due at the end of March. At the moment you'll have to make do with beta 4, which was made available this week and contains a few new enhancements, including an improved download manager.
Firefox 3 beta 4 Mac users may find that the user interface has been updated again, more in line with the Windows version. We've tested both the Windows and Mac versions of Firefox 3 beta 4 and, although the Windows version seems stable, the Mac edition had a few issues and caused a few instant crashes.
Firefox 3 beta 4 (Windows at least) is possibly usable for your day-to-day web browser, but remember that many of your existing addons, extensions and themes will not be usable with the new release.
