Developer’s Description

By Optimal Cycling

Provides control of javascript, iframes, and plugins on Google Chrome.

NotScripts is an extension for Google Chrome. NotScripts gives you a high degree of "NoScript" like control over what javascript, iframes, and plugins runs in your browser to increase security and lower the CPU usage. It is useful to help mitigate attacks like cross-site scripting (XSS) and drive by downloads by blocking the third-party content before it even runs with it's default deny policy. You can whitelist the sites you want through an easy to use url bar icon and drop down menu.
