# How to Enable JavaScript on Windows

Web apps and browsers rely on Javascript to run interactive features, update content dynamically, and display page layouts correctly.

JavaScript is a standard programming language that allows web pages to be interactive. If JavaScript is turned off, many modern websites (including online banking, streaming services, and social media platforms) will not load correctly, buttons might not work, and interactive elements will disappear.

Because JavaScript runs directly inside your web browser, **enabling JavaScript on Windows means turning it on within the browsers you use.** Here is how to enable JavaScript across the most popular browsers on Windows.

## Google Chrome

1.  Open Chrome and click the **three vertical dots** in the top-right corner, then select **Settings**.
    
2.  In the left-hand sidebar, click **Privacy and security**.
    
3.  Click on **Site Settings** in the main window.
    
4.  Scroll down to the _Content_ section and click on **JavaScript**.
    
5.  Select the radio button for **Sites can use JavaScript**.
    

## Microsoft Edge

1.  Open Edge and click the **three horizontal dots** in the top-right corner, then select **Settings**.
    
2.  In the left-hand sidebar, click on **Cookies and site permissions**.
    
3.  Scroll down the main menu until you find the _All permissions_ section and click on **JavaScript**.
    
4.  Toggle the switch next to **Allowed (recommended)** to the **On** position.
    

## Mozilla Firefox

By default, JavaScript is deeply integrated and fully enabled in Firefox. There is no simple checkbox in the standard settings menu to turn it off. However, if it was accidentally disabled through advanced settings, here is how to turn it back on:

1.  Open Firefox, type `about:config` into the address bar, and press **Enter**.
    
2.  A warning screen will appear. Click **Accept the Risk and Continue**.
    
3.  In the search bar at the top of the page, type: `javascript.enabled`
    
4.  Look at the column labeled **Value**. If it says `false`, double-click the row (or click the toggle button on the far right) to change it back to **true**.
    

## Brave Browser

Brave is built with privacy in mind and features built-in "Shields" that can sometimes block scripts.

1.  Open Brave and click the **three horizontal lines** in the top-right corner, then select **Settings**.
    
2.  Click on **Shields** in the left-hand menu.
    
3.  Look for **Block fingerprinting** or **Script blocking** options and ensure they are set to standard or disabled if they are causing websites to break.
    
4.  Alternatively, click the **Brave Shield icon** (the lion icon) directly inside your URL address bar on a specific website to disable script blocking just for that trusted site.

## How to Verify JavaScript is Working

Once you have enabled JavaScript using the steps above, you can easily test it:

1.  **Refresh the page:** Go back to the website that wasn't working and press `F5` or click the reload button.
    
2.  **Use a testing tool:** If you are still unsure, visit a free testing website like `www.enable-javascript.com`. The site will instantly detect your browser settings and tell you explicitly whether JavaScript is successfully running.
