Tough luck. The overwhelming majority of Mozilla's revenue is from their search partnership with Google, the Internet's largest advertising company. You don't bite the hand that feeds you.
Apple is the only major browser vendor that can afford to ship an ad blocker without strangling its own throat. If Jobs where still around, he might have actually done that, if only to stick a big middle finger at Google. Now I'm not so sure. Maybe MSFT will do it first with IE, if Bing's market share gets any lower than it already is (or if Yahoo finally folds).
