As it marked the 75 millionth download of its Firefox Web browser, the Mozilla Foundation said it was expanding in several directions.

The Mozilla staff itself has quadrupled during the past six months, to 40 employees.

Mozilla on Tuesday marked the 75 millionth download of Firefox. That number has only a hazy relationship to the number of people actually using the browser; it counts multiple downloads of different versions and doesn't count Mozilla's automatic updates or copies from single downloads distributed through organizations by technology managers.
