While participation in the whitelisting process was free for small websites, large advertising companies were required to pay a fee in order for their ads to be whitelisted. In 2011, Adblock Plus and Eyeo attracted considerable controversy over its 'Acceptable Ads' program to 'allow certain non-intrusive ads' (such as Google AdWords) to be allowed under the extension's default settings. The extension has been released for Mozilla Firefox (including mobile ), Google Chrome, Internet Explorer, Microsoft Edge ( Chromium based version), Opera, Safari, Yandex Browser, and Android. It is developed by developer Wladimir Palant's Eyeo GmbH, a German software company.
