This article provides instructions on how to turn on JavaScript in your web browser.

JavaScript is a programming language that website owners can use to add interactive features to their sites, making them more user-friendly. For example, you may have come across websites that have pop-up windows, or that allow you to play games or take surveys without having to leave the page you’re on. These days, JavaScript is used extensively on all sorts of websites, and it’s become an essential tool for web developers.

In order to view most of the content on the web, you’ll need to have JavaScript turned on in your browser. Below we’ll explain how to do this for the most popular browsers currently available.

What is JavaScript?

JavaScript is a programming language that can run in your web browser. It makes web pages more interactive by letting you use things like animations and forms. Many websites use JavaScript.

JavaScript is not the same as Java. They are two different programming languages.JavaScript is usually used for small pieces of code that run in your web browser. It is not used for large applications like Java is.

You don’t need to know how to program to use the internet. But if you want to, you can learn JavaScript and make your own web pages with it.

How to turn on JavaScript in different browsers

If you’re having trouble with a website, it’s possible that JavaScript is disabled in your browser. Here’s how you can turn it on in different browsers.

Google Chrome

Open Google Chrome. In the upper-right corner, click the three dots icon, then Settings. At the bottom, click Advanced. Under “Privacy and security,” click Content settings. Click JavaScript. Turn on Allowed (recommended).

Mozilla Firefox

JavaScript is a standard scripting language that is included in web pages and applications in order to make them more interactive. In JS, buttons, links, and other elements can be used to call up new content without having to reload the entire page.

Unfortunately, because JavaScript can be used for malicious purposes, some browser manufacturers disable it by default. But don’t worry — it’s easy to turn JS back on. Here’s how:

For Mozilla Firefox:

1. Open Mozilla Firefox.
2. In the upper-right corner of the screen, click the menu button (three horizontal lines).
3. Select “Options.”
4. In the left sidebar, select “Content.”
5. Check the box next to “Enable JavaScript.”
6. Close the about:preferences page. Any changes you’ve made will automatically be saved.

Microsoft Edge

Microsoft Edge is a web browser developed by Microsoft. It was first released for Windows 10 and Xbox One in 2015, then for Android and iOS in 2017, and finally for macOS in 2019.

Microsoft Edge uses the EdgeHTML engine. Starting with the October 2018 Update, Microsoft began to use the Chromium open-source project to develop Microsoft Edge on the desktop. This move allows Microsoft to better improve web compatibility and adopt new web technologies more quickly.

To turn on JavaScript in Microsoft Edge:

1. Open Microsoft Edge and click on the three dots in the top right corner of the screen to open the menu.
2. Click on Settings.
3. Click on View advanced settings.
4. Toggle the switch next to Use JavaScript to On position.


JavaScript is enabled by default in Safari. To verify that JavaScript is enabled or to enable it, follow these instructions:

3. JavaScript is now enabled.
