June 17th is the launch date for Firefox 3. Mozilla is trying to set a Guinness World Record for most software downloads in 24 hours. As a web developer, I use Firefox along with a slew of add-ons to debug my sites. I also have a lot of add-ons that make my browser so much more efficient. I’ll be downloading it tomorrow. If you want to join in, the Firefox peoples have set up a Download Day 2008 site. Download Day starts at 10:00 a.m. Pacific Daylight Time on Tuesday, June 17th.
