We're big fans of the Firefox 3 betas at EPIC FU. It runs faster, eats up less memory, and generally speaking we like the new features, e.g. the almighty location bar. Also, the Mac theme is much more Mac-like. Did I mention we like Macs?
Firefox is hoping to break a Guinness world record for the number of downloads in a day when the final Firefox 3 browser is released. Over a million people have already pledged to participate.

The exact release date isn't known yet, but the word on the street is sometimes in early July. If you pledge to download, the folks at Spread Firefox will send you a reminder email when the date is known.
