Add-on summary

Winner of the "PC World - World Class Award" and bundled with the Tor Browser, NoScript gives you the best available protection on the web. It allows JavaScript, Flash, and other executable content to run only from trusted domains of your choice (e.g. your banking site), thus mitigating remotely exploitable vulnerabilities, such as Spectre and Meltdown.

It protects your "trust boundaries" against cross-site scripting attacks (XSS), cross-zone DNS rebinding / CSRF attacks (router hacking), and Clickjacking attempts, thanks to its unique ClearClick technology.

Such a preemptive approach prevents exploitation of security vulnerabilities (known and unknown!) with no loss of functionality where you need it. Experts do agree: Firefox is really safer with NoScript!
