NoScript does its job well. I feel safe browsing the web with this extension preventing malicious scripts from running.

On top of that, I'm glad this extension can be used on the mobile version of Firefox.

A must-have for any Internet user. Install it and be amazed at the wondrously vast and juicy attack surface your bank and other top sites provide to attackers by running 3rd-party scripts :-)

A must-use extension. In addition to security, very powerful for ad-blocking and tracker management.

Great add-on! If it's recommended by PrivacyTools.io and even implemented into the TOR Browser, it's good on my book. If you haven't checked them out, they have other solid privacy recommendations.

Super

Perfect for manually handling all the javascript.
More user friendly than option offered by uBlock.
