Advertising is the business model of the Web, Mozilla concedes. But the non-profit foundation behind the Firefox web browser has so far been unable to adopt that. It has tried, of course, and got no small amount of backlash because of its standing in the open source and privacy-conscious community. Despite setbacks, it’s trying again, this time with a little help from save-for-later service Pocket. Which, by the way, Mozilla owns since February last year.
