NoScript

A free extension for Mozilla Firefox and other browsers, NoScript aims to protect you against trackers, advertisements, and other potentially harmful and unwanted content by blocking JavaScript and other scripts running on a webpage.

Pros

• Available for most browsers
• Allows exporting settings
• Free to use
• Protects privacy and security
• Customizable settings
• XSS protection

Cons

• Requires a lot of manual effort
• Can be time-consuming to set up
• Whitelists some sites by default

NoScript is one of the most useful script blocking extensions available for Mozilla Firefox, Google Chrome, SeaMonkey, and other browsers. It is a freeware that, once installed, adds a handy button to the toolbar of the browser. Clicking on this button displays a list of domains running scripts on the page. You can block or allow each of these domains and sub-domains depending on your preferences.

This extension provides an effective way to block trackers, advertisements, and other harmful content. It not only helps increase your privacy and security when surfing the web but also improves page load times by blocking downloads from third-party domains. By default, the active scripts are blocked globally though users get the option to block specific unwanted content.

NoScript is also a useful tool for developers who want to see how their site functions without JavaScript. It even helps remove frustrating web elements like pop-up messages. The interface can be accessed by either right-clicking on the page or using the dedicated box at the bottom, which displays the URLs blocked.

Conclusion

Though NoScript may seem to be difficult to set up for beginners, it requires a little effort to set up and start using and is quite handy for techies. Every website you set up with NoScript remains so for an indefinite time, improving your privacy and security on the internet. You can also export your preferences to other systems for added convenience. It is overall an excellent extension for those who want some control on scripts running on their web browser.
