All that is irrelevant to what I just said, and what you originally said, but for the record, I’m not mad about it. Firefox is implementing ads in a privacy-friendly way and, now that they’re basically the only browser engine in the world that isn’t Chromium and their Google money is drying up, they’re going to have to earn revenue somehow. No way in hell they’re going to live off donations, and if they start charging for the browser, their entire userbase – and with it their ability to influence W3C standards – will disappear faster than you can blink. If they do that by selling privacy respecting ads, I’m all for it.
