Properties

A release of pages via a positive list or only temporarily until you close your browser. Blocked pages are locked within allowable pages and executed only after a special approval.

An import and export function allows you to secure the positive list, for example, when reinstalling the browser. The synchronization of shares between different installations is possible.

XSS protection

NoScript provides protection against cross-site scripting, which prevents third-party content can perform malicious code in a shared website. Exceptions to this can be created using regular expressions.

ClearClick

A ClearClick Protection detects attempts by clickjacking and alerts the user with a warning, and other ways out.

Criticism

NoScript opens by default after each update without asking the manufacturer's website. This can be " Notifications " " after an update Release Notes " under off by removing the tick in the settings of the extension in the tab. Moreover, had the author of NoScript, Giorgio Maone that can put advertising on his side through his program on the White List for Adblock Plus. This was not to be undone by the user. Later, these grievances have been resolved due to heavy criticism.
