Mozilla Corp, creator of the popular Firefox web browser, said on Thursday it would follow Google Inc and no longer recognize new certificates of trust issued by a Chinese Internet agency.

Firefox is famous for its addons, and for good reason: they can make your browser do just about anything. But which addons are the most useful? Here are the addons we think are best, what they do, and where you can find them.

Google's 10-year run as Firefox's default search engine in the US is over. Yahoo wants more search traffic, and a deal with Mozilla will bring it.

The Humble Mozilla Bundle focuses on Indie games, the fastest growing games category. These range from new titles like Democracy 3 to some of the most popular indie titles from short (FTL) to long (AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome). All make use of Mozilla-pioneered asm.js and the other powerful technologies that make plugin-free gaming possible on the Web, allowing users to jump right into the action from just clicking a link.

The open-source browser gets a proprietary Adobe software so people can watch video from sites like Netflix over the Web. Supporting it is better than losing Firefox users, Mozilla says.
