You can say what you want about Mozilla’s attempts at earning money but you can’t criticize it for lack of trying. In fact, the non-profit open source organization has a knack for throwing out ideas and experiments and getting users to be their guinea pigs. Or brave testers, if you will. Those experiments all came from the Firefox Test Pilot garage, which is sadly now closing up shop. Mozilla assures fans of the browser, however, that experiments will stop. In fact, it promises there will be even more.
