Adblock Plus supports the Acceptable Ads initiative. Acceptable Ads are shown by default, which helps support websites that rely on advertising revenue but choose to only display nonintrusive ads. This can be disabled at any time for users who wish to block all ads. The initiative allows content producers to receive monetization for their work and helps create an environment of fairness and sustainability for user, advertiser, and creator alike. Learn more
