Mozilla is blocking the automatic loading of plugins like Java, Silverlight and QuickTime and putting in place a ‘Click and Play’ feature with an eye on improving the performance of its browser Firefox. In a blog post, Michael Coates, director of security assurance at Mozilla, said poorly designed plugins are a reason for browser crashes and security breaches. Loopholes allow hackers to gain control of the device. “Click to Play allows users to easily choose if they wish to run a plugin on a particular site. Users can also configure sites to never run plugins or conversely always run plugins,” says Coates. Apple has also blocked Java from Mac browsers because of security fears.
