Four short years after Firefox 1.0 started to "reclaim the web," Firefox 3.0 has arrived! So help set a Guinness World Record (for most software downloads in a 24-hour period) and get Firefox 3 today here. (Or, the direct download link here.)
I've been using the release candidates for over a month now, and I can wholeheartedly recommend it for anyone to use.
Do it! All the cool kids are! ;)
