Mozilla is looking for guinea pigs to try out the new version of its browser, Firefox 3 Beta 1. Mozilla calls itself a "foundation" and its slogan is "Good for the Web. Good for the World." But you know better than that. Mozilla topper Mitchell Baker makes $500,000-plus a year and Mozilla's for-profit wing brought in $56 million in revenues last year. In other words, no one should feel obligated by a sense of charity to download the new beta software. Baker & Co. could afford to pay for some actual QA engineers.
