For the past few weeks, the folks in the Mozilla community have been writing extensively about the new and improved features you’ll see in the browser. The new features run the gamut from huge and game-changing to ones so subtle you may not notice them until you realize that using Firefox is just somehow easier and better. The range of improved features is similar — whole back-end systems have been rebuilt from scratch, while other features have been tweaked slightly or redesigned in small ways. Overall, the result is the fastest, safest, slimmest, and easiest to use version of Firefox yet. To find out more, read the Field Guide to Firefox 3.

If you haven’t yet, you should also go to the Firefox Download Day site and help set a new Guinness World Record for the most software downloaded on a single day. Once you’re done there, head over to Mozilla Party Central and find or set up an event to take part in. We hope you’ll all join in helping us celebrate the release of the best Firefox ever.
