Firefox 3.0, the latest version of the popular open source web browser, is attempting to set a world record for software downloads in a single day.

On Tuesday June 17, over 1.3 million people (as of this writing) have pledged to download the new version of the software.  I've been using a beta release of the software for a month or so and have to say it's a massive improvement over the current release.
