Free, open source browser extension for Firefox, Chrome, and other browsers, allowing users to selectively enable and disable JavaScript, Java, Flash and other plugins on a site-by-site basis for security and privacy reasons.
NoScript is a free, open source browser extension available for Firefox, Chrome, and other browsers. It provides users with a powerful tool to control JavaScript, Java, Flash and other plugins on websites they visit.
By default, NoScript blocks all scripts on web pages. Users can then selectively allow scripts on a site-by-site basis. This gives users more control over security and privacy while browsing. Malicious scripts are blocked by default, limiting exposure to potential threats from questionable sites.
In addition to blocking scripts, NoScript provides protection against clickjacking attacks, cross-site scripting (XSS) attacks and other web-based exploits. It also hides the user's IP address from untrusted sites to improve anonymity.
For experienced users, NoScript delivers unparalleled control over the browser environment. But it also includes configurable whitelisting and blacklist capabilities to automate permissions for non-technical users. The extensive set of security and privacy features has made NoScript one of the most popular Firefox addons for many years.
