The Mozilla Foundation has come out against ad blocking:<p>&quot;Content blocking software should focus on addressing potential  user needs  (such as on performance, security, and privacy) instead of blocking specific types of content (such as advertising).&quot;[1]<p>This is sad. Their slogan used to be &quot;Work for mankind, not for the man&quot;.  But the Mozilla Foundation is ad-funded. They currently have a deal with Yahoo to make Yahoo Search their preferred search engine. Before that, it was Google. Those deals bring in hundreds of millions of dollars a year. So they can&#x27;t afford to bite the hand that feeds them.<p>This places them in conflict with Apple.  Apple makes their money selling stuff to end users at a high markup. They can be very anti-advertiser if they choose.  Apple could block all ads on their devices and market that as a feature.<p>[1] <a href="https:&#x2F;&#x2F;blog.mozilla.org&#x2F;blog&#x2F;2015&#x2F;10&#x2F;07&#x2F;proposed-principles-for-content-blocking&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.mozilla.org&#x2F;blog&#x2F;2015&#x2F;10&#x2F;07&#x2F;proposed-principles...</a>
