|Abstract: ||With the rapid proliferation of the internet, web browsers have evolved from single-purpose remote document viewers into multifaceted systems for executing dynamic, interactive web applications. In order to enhance the web browsing experience of users and to facilitate on-demand customizability, most web browsers now can be fitted with extensions: pieces of software that utilize the underlying web platform of a browser and provide a wide range of features such as advertisement blocking, safety ratings of websites, in-browser web development, and many more. Extensible web browsers provide access to their powerful privileged components in order to facilitate the development of feature-rich extensions. This exposure comes at a price, though, as a vulnerable extension can introduce a security hole through which an attacker can access the privileged components and penetrate a victim user’s browser, steal the user’s sensitive information, and even execute arbitrary code in the user’s computer. The current browser security model is inadequate for preventing attacks via such vulnerable extensions. Therefore, an effective protection mechanism is required that would provide web browsers adequate security while still allowing them to be extended.
