NoScript is an open-source browser extension designed to improve web security by blocking JavaScript, Java, Flash, and other potentially harmful active content by default. Available for Firefox, Chrome, and other Mozilla- and Chromium-based browsers, it gives users complete control over which websites are allowed to execute scripts. After using NoScript, I found that its whitelist-based approach offers strong protection against malicious websites while allowing trusted sites to function normally. Combined with advanced anti-XSS and anti-clickjacking defenses, it provides an extra layer of browser security for users who want greater control over web content.
