How to Enable JavaScript on Android in 4 Easy Steps

Have you ever visited a website on your Android phone only to find that certain features don’t work? Maybe the website is telling you to enable JavaScript? If you’re still finding your way around the interwebs, chances are, that would leave you stumped. Don’t worry though. Enabling JavaScript on your Android device is a quick and easy process. In this guide, we’ll walk you through the steps to enable JavaScript on Android so that you can access all the features on your favorite websites.

What’s JavaScript and Why Would I Need to Enable It Anyway?

Modern websites owe most of their flash and pomp to the magic of JavaScript. Behind all the animations and shiny buttons, there’s a whole lot of JavaScript going on. As it’s often referred to, JavaScript is the programming language of the web.

JavaScript is mostly used on the client-side of websites, that is, everything you as the user interacts with. It allows for the creation of interactive and dynamic web content, such as drop-down menus, pop-up windows, and other user-interface elements.

With every YouTube video you watch or gadget you purchase on Amazon, you’re interacting with JavaScript in some way. And if you want to fully enjoy everything the web has to offer, you need to make sure that you have JavaScript enabled on your phone.

However, it’s not just about enjoying all the bells and whistles that websites have to offer. Enabling JavaScript on your phone also helps keep you safe while browsing the web. Websites use JavaScript for security purposes, like validating login information or encrypting sensitive data.

As websites get more complex with the addition of different functionalities, by enabling JavaScript, you’re ensuring that you’re able to access all the features they have to offer. This in turn makes your browsing experience more productive and seamless. 

How to Enable JavaScript on Android

Assuming you’ve disabled JavaScript and are trying to access a site like Tesla.com, you may notice that the site loads quickly albeit with limited functionality. Only basic text and images will load, and the site’s normal image-scrolling animations will be non-functional. Follow the steps below to enable JavaScript on your Android device.

Step 1: Open Your Android Browser Settings

The first step in enabling JavaScript on your Android phone is to fire up your browser and open its settings menu. 

This may vary depending on the browser you’re using, but typically you can find the settings by tapping on the three dots in the top-right corner of your browser window if using Chrome and selecting “Settings” from the drop-down menu.

Tap on the three dots at the top right-hand corner to begin.


If you’re using a different browser, such as Samsung Internet on a Samsung Galaxy phone, you can find the menu icon in the bottom-right corner of your browser window. Proceed to click on “Settings”.

Step 2: Access Your Site Settings

After accessing your browser settings, scroll down to the option labeled “Site settings” or some similar option, depending on your browser. You can find it under the “Advanced” settings section of your Chrome browser.

Under Advanced, scroll down until you locate site settings.


Meanwhile, the option is labeled “Sites and downloads” on Samsung Internet. Click on it and then tap on “Site permissions.”

Step 4: Refresh Your Page

After you’ve enabled JavaScript, you’ll need to refresh the page you were trying to access. This will ensure that the website recognizes that JavaScript is now enabled on your phone, and you can now access all the features that were previously unavailable.

When you refresh the page, you will see that the interactive elements are now working.


You’ll now notice that interactive elements on the page such as menus or image animations are back to working correctly. You may also realize, depending on your internet connection and device capabilities, that the page tends to load a bit slower compared to when JavaScript was disabled. 

That’s just one of the trade-offs of enabling JavaScript, but the improved functionality and interactivity of website of the website clearly outweigh the slightly slower loading times in the Tesla website case.

If you’re still having issues after enabling JavaScript, try restarting your browser or clearing your browser cache and cookies. This can often help fix any lingering issues that may be preventing you from accessing certain website features. You could also try visiting the page in an incognito or private tab to see if it still behaves the same.

Site Exceptions

In some cases, you may want to disable JavaScript on specific websites while keeping it enabled on others or vice versa. For example, you may be concerned about the security implications of enabling JavaScript on a particular website, or you may find that the website’s JavaScript-heavy features are causing your phone to slow down.

Fortunately, Android browsers like Chrome allow you to set site-specific exceptions for JavaScript. This means you can enable or disable JavaScript on a per-site basis, giving you more control over your browsing experience.

Instances When You’d Need to Disable JavaScript on Your Phone

As we’ve seen, enabling JavaScript is mostly a good idea if you’d like to make the most of your browsing experience. However, there are some cases where you might want to keep it disabled. Besides performance and security, disabling JavaScript can also potentially help protect your privacy. Some websites use JavaScript to track user activity and gather personal information. By disabling JavaScript, you can prevent this type of data collection.

However, please remember that disabling JavaScript can result in some website quirks, as many sites rely heavily on JavaScript for their functionality nowadays. We therefore only recommend disabling JavaScript when absolutely necessary. If you’re unsure, you may want to consider using the site exception feature to selectively enable JavaScript for specific sites while leaving it disabled for others.

Frequently Asked Questions

Will disabling JavaScript stop ads and popups on my phone?

Disabling JavaScript can reduce the number of ads and popups you see on your phone, but it’s not a foolproof solution. Many websites and apps use other methods to display ads and popups that do not rely on JavaScript.

Would apps like Facebook, Reddit, or Twitter work on my phone with JavaScript disabled?

Unless using a browser app, you don’t have to worry about enabling JavaScript as native apps like Facebook, Reddit, and Twitter should work just fine on your phone even if JavaScript is disabled. Most native apps do not rely on JavaScript for their basic functionality.

Can I enable JavaScript on my Android phone for only certain websites?

Sure, you can enable JavaScript for specific websites. As we saw, some browsers like Chrome have a site exception feature that allows you to enable JavaScript only for certain websites.

Will enabling JavaScript on my Android phone increase my data usage?

Enabling JavaScript will probably increase your data usage (albeit minimally) as some websites may use JavaScript to load additional content or advertisements.

Will enabling JavaScript on my Android phone affect my device's performance or battery life?

Enabling JavaScript on your Android phone may slightly impact device performance and battery life, as JavaScript requires some processing power to function. However, the impact is generally negligible, and enabling JavaScript will not significantly affect the overall performance or battery life of your device.

How can I test if JavaScript is enabled on my Android device?

You can simply visit a website that requires JavaScript to function properly, such as Google Maps or Facebook. If the website loads and functions normally, then JavaScript is likely enabled on your device. But if certain features on the website aren’t working as expected, or if you see error messages, then JavaScript may be disabled.
