Overview of NoScript (Protection for your browser)
NoScript also provides the most powerful anti-XSS and anti-Clickjacking protection ever available in a browser. NoScript's unique whitelist based pre-emptive script blocking approach prevents exploitation of security vulnerabilities (known, such as Meltdown or Spectre, and even not known yet!) with no loss of functionality...
It protects your "trust boundaries" against cross-site scripting attacks (XSS), cross-zone DNS rebinding / CSRF attacks (router hacking), and Clickjacking attempts.
