Huh? I was connecting the dots. Most corporations won't leave Firefox 3.6 because of the rapid release cycle of Firefox. The extended support is for these companies. Regular consumers will be happy with the silent update every six weeks. If most corporations buy into the new ES version then 3.6 will be practically gone in a matter of months. This is important because FF 10+ is a vast improvement over 3.6, and soon developers will be able to assume FF 10+.
