Yet another Firefox browser developer employee (thanks, Blake) has left, but this time not for Google. Bart Decrem has left to form a Palo Alto start-up called Round Two, though this time stays within the growing Mozilla development ecosystem. According to its release today, the company wants to make the Firefox web browsing experience “even more fun, safe and productive by offering a variety of user-friendly products and innovative services aimed at Firefox users. The company will launch initial products and services in the spring of 2005.” Decrem headed marketing and business affairs for the Mozilla Foundation.
