The excellent NoScript extension is well maintained and updated by developer, Giorgio Maone, who quickly answers questions on forums.informaction.com.

Вже через дві години Я не уявляю життя без цього додатку.

This extension does it all, protects privacy, ad block, and it even allows you to stop secret http connections.

A very useful add-on. Thank you very much.

It prevents scripts from running on the websites you visit which is really cool. However you would need to manually enable scripts on sites that you know are safe and want to use.

On average it will make sites load faster as many useless scripts (that track user activity and other things) will not run anymore. It is really cool to only allow what functionality you need from the sites you visit.
