I am surprised by your comment and the reaction to mine. Why would firefox's users be alienated? They get an adblocker by default that will be supported and maintained by mozilla. If you want to block all ads that would be changing a setting, what google and pals pay for is the default setting that benefits them, they will still get blocked if users want them blocked. This mindset of making an emotional ideologic reaction isn't helping anyone!

> If a way to serve unblockable ads existed, it would already be implemented and widely used

It would require a change in how ads are served and bids are made in realtime. The main reason it isn't happening already is that most people are not blocking ads, especially on mobile where engagement has most value.I'd say ad blocking users are not more than firefox users even.
