Firefox 3 Final isnt available to download directly yet, but it has been found in the FTP Server of mozilla.org.
Those who are too desperate to download it (like me) can download it from ftp://ftp.mozilla.org/pub/firefox/releases/3.0/win32/en-US/Firefox Setup 3.0.exe
This is not any joke or anything. It’s for real! I have also downloaded it and it’s working really great! 
If you download Firefox 3 from here, your download wont be counted in the Firefox 3 pledge, if you want your download to be counted, then don’t download now or you can download it 2 times
We’re not quite ready yet!
We’re just as excited as you are for our upcoming release, but we’re still putting the finishing touches on Firefox 3: preparing the new mozilla.com website, getting our severs ready for downloads, and doing our final pre-launch checks. You can follow our progress if you’d like!
The files in this directory are - for now - only meant to be used by our testers. Downloading them directly can harm our ability to distribute Firefox efficiently, and will also not be counted as part of our attempt to set a Guiness World Record for the most software downloads in a day.
If you’d like to be notifed the minute that we launch, please go to sign up for Download Day. Or just head over to getfirefox.com on Tuesday, June 17th after 10am PDT.
With over 1 million pledges, it certainly looks that Mozilla Firefox will set the record for most software downloads in 24 hours.
