Firefox Tops 400 Million Downloads

Less than two years after it crossed the 100 million mark, total downloads of Mozilla's Firefox Web browser have now passed 400 million, although the number does not represent total installations. Since the release of Firefox 2 last October, the browser has continued to take market share from IE.

Mozilla is now working on version 3 of Firefox, which is currently in its alpha stages of development. The update has seen a number of delays and a beta release is not due until the fall, but that hasn't slowed adoption. According to the company, Firefox usage in Slovenia is nearing 50 percent market share, which would put it over Internet Explorer for the first time anywhere in the world.
