Mozilla has announced that Firefox 3 will be available for download on 17 June.

Following two release candidates on the PC and three on the Mac, the latest iteration of the open source browser has been declared ready for general consumption.

"After more than 34 months of active development, and with the contributions of thousands, we are proud to announce that we are ready," wrote Mike Beltzner on the Mozilla community blog.

Mozilla is pitching the launch as Download Day 2008 in an attempt to break the Guinness World Record for the largest number of downloads in 24 hours.

So far over a million users around the world have pledged to download the new browser on 17 June.
