How to Disable and Turn Off JavaScript in Google Chrome Browser

JavaScript is a programming language that powers many features and functions on websites. When enabled in your web browser, JavaScript allows sites to provide interactive elements, animations, popups and more.

However, there may be times when you want to disable JavaScript in your browser for security, privacy or troubleshooting purposes. Fortunately, Google Chrome makes it easy to turn off JavaScript completely or on a site-by-site basis.

Why You Might Want to Disable JavaScript

Here are some common reasons for disabling JavaScript in Chrome:

  • Enhanced security and privacy: JavaScript can be used to run malicious code or access information about you and your browsing habits without consent. Disabling it prevents this potential privacy violation.
  • Website troubleshooting: If a site is not behaving properly or has performance issues, temporarily disabling JavaScript can help determine if the problems are due to JavaScript errors or conflicts.
  • Reduced resource usage: JavaScript is used to power interactive site features, which can consume additional memory and CPU resources. Disabling it can help pages load faster and extend battery life.
  • Accessibility: Some users with disabilities use assistive technologies like screen readers that may not interact well with JavaScript. Turning it off can improve accessibility for those users.

How to Disable JavaScript in Google Chrome

There are a few different ways to disable JavaScript in the Chrome browser.

Disable JavaScript via Settings

  1. Click the three-dot menu button in the top-right Chrome toolbar
  2. Select Settings
  3. Click Privacy and security in the left sidebar
  4. Select Site settings
  5. Scroll down and click JavaScript
  6. Turn off the Sites can use JavaScript toggle switch

This will completely disable JavaScript in Chrome until you re-enable it.

Disable JavaScript via Developer Tools

You can also easily turn off JavaScript on a tab-by-tab basis using Chrome’s built-in Developer Tools:

  1. Open the site you want to disable JavaScript on
  2. Right click anywhere and select Inspect
  3. Open the Command Menu with Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac)
  4. Start typing “javascript” and select Disable JavaScript
  5. Press Enter to run the command

JavaScript will remain disabled on that tab only until you close or reload DevTools.

Disable JavaScript on Specific Sites

Under the JavaScript settings, you can also choose to disable JavaScript on a site-by-site basis:

  1. Follow steps 1-5 under Disable JavaScript via Settings above
  2. Under Behavior, click Add
  3. Enter the URL of the site you want to block JavaScript on
  4. Click Add

You can add multiple sites here that will have JavaScript disabled whenever you visit them.

Re-Enabling JavaScript in Chrome

Once disabled, re-enabling JavaScript in Chrome is easy:

  • To re-enable JavaScript globally, simply toggle the Sites can use JavaScript switch back on in Settings.
  • If you disabled JavaScript via Developer Tools, reloading the tab will re-enable it.
  • To re-enable JavaScript on specific sites you blocked, go back to Settings > Site Settings > JavaScript and remove the sites from the Block list.

And that’s it! With these simple steps you can easily disable JavaScript across all sites or on specific ones only in Google Chrome for security, troubleshooting or any other necessary reason.

Frequently Asked Questions

Is disabling JavaScript safe?

In most cases, yes. The majority of websites are designed to degrade gracefully with JavaScript disabled, meaning core functionality should still work. However, some sites rely heavily on JavaScript and may not work properly with it off.

What happens when I disable JavaScript?

When disabled, JavaScript code will not execute on websites you visit. This means interactive features like drop-down menus, sliders, forms, or scrolling effects may not work properly or at all on some sites. Pages will be more static.

Will turning off JavaScript break websites?

Some websites that rely heavily on JavaScript may not display or function correctly with it disabled. However, many sites will still work reasonably well but be less dynamic and interactive. Test with JavaScript off first before relying on it for critical tasks.

Is there a way to selectively enable JavaScript for some sites?

Yes! Chrome allows you to customize JavaScript behavior on a per-site basis even when globally disabled. Under Site Settings, you can explicitly allow or block JavaScript on specific domains you specify. This gives you fine-grained control.

What’s the easiest way to temporarily disable JavaScript on a site?

The fastest way is to disable JavaScript site-wide is via the Developer Tools. Just opening DevTools, running the “Disable JavaScript” command and reloading disables JavaScript on that tab only without having to mess with settings.

Conclusion

JavaScript powers much of the interactivity and functionality on modern websites. But security, privacy or troubleshooting needs may arise where disabling it is useful.

Luckily Chrome makes it simple to turn off JavaScript in just a few clicks globally or on specific sites only. Just dive into Settings, Site Settings or Developer Tools to disable JavaScript across all sites or a select few in a matter of seconds.

Being able to selectively block JavaScript also helps strike the right balance between functionality, security and privacy based on your browsing needs.
