How to Turn On JavaScript in Your Browser

JavaScript is a crucial part of modern web development, enabling interactive features on websites. If you’re having trouble with websites not working as expected, JavaScript might be disabled in your browser. This guide will show you how to enable JavaScript in various browsers.

Why Enable JavaScript?

JavaScript powers dynamic content, animations, forms, and more. Without it, many websites will function incorrectly or not at all. Enabling JavaScript ensures you have the full web experience.

Enable JavaScript in Google Chrome

Open Chrome and go to Settings (three dots in the top-right corner > Settings).
Scroll down and click on Privacy and Security.
Select Site Settings.
Under Permissions, click on JavaScript.
Ensure the toggle is On.

- **Note:** If you're on a specific site, you can enable JavaScript just for that site by visiting `chrome://settings/contentExceptions#siteSettings`.

Enable JavaScript in Mozilla Firefox

Open Firefox and go to Settings (three lines in the top-right corner > Settings).
Click on Privacy & Security.
Under Permissions, click on JavaScript.
Select Allow websites to request to run JavaScript.

Enable JavaScript in Microsoft Edge

Open Edge and go to Settings (three dots > Settings).
Click on Privacy, search, and services.
Scroll down to Permissions and click on JavaScript.
Ensure JavaScript is Enabled.

Enable JavaScript in Safari

Open Safari and go to Safari > Preferences.
Click on the Websites tab.
Select JavaScript from the left menu.
Check Allow JavaScript.

Enable JavaScript on Mobile Browsers

For mobile browsers like Chrome, Firefox, or Safari, the process is similar:
1. Open your browser’s settings.
2. Navigate to the permissions or site settings section.
3. Enable JavaScript.

Check if JavaScript is Enabled

You can test JavaScript by running a simple script in your browser’s console:

// Open the browser console (F12 or right-click > Inspect > Console)
console.log("JavaScript is enabled!");

Or visit a website like javascripttest.com to check.
