What is NoScript?

NoScript is a powerful Chrome extension designed for maximum web protection. It works by allowing JavaScript, Flash, Java, and other executable content to run only from trusted domains, such as your home-banking site. This technique mitigates the risk of remotely exploitable vulnerabilities like Spectre and Meltdown. It offers a solid defense against cross-site scripting attacks (XSS), cross-zone DNS rebinding, CSRF attacks (router hacking), and Clickjacking attempts. This preemptive approach helps prevent exploitation of even unknown security vulnerabilities without causing any loss of functionality where you need it. Considered the best available protection on the web, NoScript has won the 'PC World World Class Award' and is bundled with the Tor Browser.
