Jinshan stated that CM Browser's ad filtering feature was vendor-neutral and that users must opt-in to activate the feature. In the preceding trial, Youku claimed to suffer an economic loss as a result of CM Browser's ad filtering, as the company earned revenue from ads and premium subscriptions that allowed users to skip ads. On September 21, 2014, Jinshan was ordered to pay Youku ¥300,000 for violating Chinese competition laws by allowing CM Browser to filter video ads on Youku's website. This prevented the use of the Chrome Web Store on CM Browser. Version 1 of CM Browser used version 17 of Chromium, which was much lower than the official version of Chromium. On June 3, 2013, CM Browser was released on Android and iOS. Jinshan Network claims that CM Browser is the first secure dual-engine browser with a 'browser intrusion prevention system'. The browser is based on Chromium and supports both the WebKit and Trident browser engines.
CM Browser ( Chinese: 猎豹安全浏览器) was a web browser developed by Cheetah Mobile.
