Whether you still use Firefox or not, the company has some news: It's pulling ads from the Tiles that pop up when a new tab is opened. The company says that the move is the result of learning what its users want (content that's "relevant, exciting and engaging") and that it'll use the free spaces to help enable discovery of said content. But this won't happen overnight. VP of content services Darren Herman writes that Mozilla will of course honor its obligations with its advertising partners and will gradually end the program over the next few months.
