Does Disabling JavaScript Protect You From Hackers? | #computerhacking | #hacking | #hacking | #aihp

JavaScript is responsible for many elements in a web page. As you read this on any mobile or desktop browser, it most likely supports loading up JavaScript to help you navigate the web. Some popular examples would include Twitter, GitHub, Trello, and countless others. The exceptions may include text-based webpages with no dynamic resources and classic HTML-powered websites.


Considering the majority of the web utilizes JavaScript to show image galleries, ads, pop-ups, interactive menus, maps, web apps, and more, how can disabling JavaScript actually protect you from hackers?

What Does Disabling JavaScript Do?

JavaScript is an online scripting language used extensively by websites.

Nonetheless, there are various privacy extensions and options available in the browser (Chrome, Firefox, Safari, etc.) to disable JavaScript. That makes it pretty easy to disable (and enable) JavaScript.

But, when you disable it, what really happens? Some scenarios include:

  • You get a cleaner reading experience, removing annoying pop-ups and ads (varies between websites).
  • It blocks several elements on websites that include tracking cookies, thus enhancing your privacy.
  • Disabling JavaScript can break websites too, affecting the user experience.
  • It eliminates the possibility of a hacker injecting malicious code into the web page you browse.

In a nutshell, disabling JavaScript makes the browsing experience safer, but it also comes at a cost to the user experience.

If you struggle to navigate through a website and find some elements broken, it is most likely because you disabled JavaScript for the web page.

Does Blocking JavaScript Protect You From Hackers?

Yes and no.

A hacker cannot get you to load malicious scripts from the web page you visit because you have already blocked it. If you don’t enforce the block, the malicious script can load in your browser to download a suspicious file, or anything to affect your computer.

So, with JavaScript disabled, you protect yourself from hackers in one way.

However, other security threats still lurk across different web pages. It could be something in the file that you downloaded from a website or an email. It could also be a fake website where you entered your account credentials unknowingly.

Even if you have blocked JavaScript, you still have to remain cautious, check if a link is safe, and use techniques like browser isolation to protect yourself from hackers.

How to Disable JavaScript in Chrome and Other Browsers

You can use some privacy-focused browser extensions to get more functionality and control. Again, this does mean your user experience will be affected.

In either case, you can explore content preferences (via site settings) in your Chrome browser, which can be found under the Privacy and security settings of any Chrome-based browser.

You can refer to the official documentation of any other browser you tend to use.

Should You Disable JavaScript?

While JavaScript can be exploited by hackers, you can absolutely remain safe from hackers even without disabling it.

You can choose to disable it when you think a website is bloated with JavaScript, giving you an unpleasant experience. But otherwise, you can still safely browse the web without disabling it, as long as you remain careful at all times.
