How to Enable JavaScript on Apple Safari (iPad, iPhone iOS)

Are you having a hard time in trying to turn on JavaScript on your iPad or Apple iPhone device?

JavaScript has evolved into an essential tool that makes the web what it is today. It controls the dynamic elements of web pages, and most websites will fail to run correctly if your Apple Safari browser does not have its JavaScript enabled. Although disabling JavaScript offers browsers faster loading of a website, you should know that it reduces the overall browsing experience on your iPad or iPhone device.

Be it an iPhone 11, iPhone 10 or MacOS device, the steps in this guide will help you learn the simple process and benefits of enabling the JavaScript feature on your Safari browser.

Instructions for Web Developers

You may want to consider linking to this site, to educate any script-disabled users on how to enable JavaScript in six most commonly used browsers. You are free to use the code below and modify it according to your needs.

On enablejavascript.io we optimize the script-disabled user experience as much as we can:

• The instructions for your browser are put at the top of the page
• All the images are inlined, full-size, for easy perusing

We want your visitors to have JavaScript enabled just as much as you do!

What Is JavaScript and Why Do I Need It?

JavaScript is a type of code used by web developers to install and establish interactive content on websites – in essence, it allows web pages to dynamically load and send content in the background without page loads on your Apple Safari browser. Generally, JavaScript is used by modern websites to provide various features such as display advertisements – the reason why a small subset of internet users want it disabled.

However, disabling the JavaScript feature on your Safari web browser is much more of a hassle than it seems. If you turn off JavaScript on your browser, many websites won’t function properly. In most cases, you will also be unable to enjoy certain functions or view content that you are accustomed to accessing on JavaScript-based websites.

Last Updated: March 29, 2024

Using Safari

Using google chrome, using mozilla firefox.

This wikiHow teaches you how to enable JavaScript in Safari, Google Chrome, and Mozilla Firefox when you're using a Mac. JavaScript is enabled by default in most modern web browsers or is prompted whenever an application needs to use it, so you shouldn't have to enable it unless you've turned it off.

JavaScript for Mac: Enabling in Your Browser

• JavaScript is enabled in most Mac web browsers by default, so you shouldn't have to enable it unless you've turned it off.
• To enable JavaScript in Safari, click the Safari menu, select Preferences or Settings , click Security , and check the box next to "Enable JavaScript."
• To enable JavaScript in Chrome, click the menu, go to Settings > Advanced > Site Settings > JavaScript , and toggle on the "Allowed" switch.

Things You Should Know

• Navigate to the "Security" tab of your Safari Preferences to ensure the box next to "Enable JavaScript" is checked.
• Find "Site Settings" under the "Privacy and Security" tab of your Chrome Settings to enable JavaScript.
• Firefox enables JavaScript by default. If it is disabled, you may have an extension that is blocking it.

• If you're using a browser plugin that blocks JavaScript from running on one or more websites, you'll usually need to disable it. You can do so on the Preferences panel by clicking Websites and de-selecting the plugin name. [2] X Research source

• JavaScript is allowed by default in Chrome. You shouldn't have to manually enable it unless you've turned it off.

• If you see the word "Allowed" right below "JavaScript," JavaScript is already enabled.
• If JavaScript isn't working despite being enabled, it's likely due to a security extension you've installed on Chrome. Click the ⁝ menu, click More Tools , and then Extensions . Toggle off any extensions you don't want to use.

• Chrome lets you manually disable JavaScript by website. If you manually disabled JavaScript on a certain site and want to re-enable it, you can do so under the "Blocked" header. Click the ⁝ menu next to the site's name and click Remove .

• JavaScript is enabled by default in Firefox. There's no way to disable it in your general Firefox options, so it's unlikely that you'll need to turn it on unless you've manually edited the about:config page.
• If you've installed a privacy extension like Ghostery or NoScript that disables JavaScript, you may need to disable it to use JavaScript. Click the ≡ menu, click Add-ons , and then click Disable next to the extension. [3] X Research source

• The results appear in three columns: Preference Name , Status , Type , and Value .

• If the Value is set to True : JavaScript is already enabled and there's no need to make any changes. Do not continue with this method.
• If the Value is set to False : Continue with this method.

iOS 17: How to Enable JavaScript on iPhone in Simple Steps

Enabling JavaScript on your iPhone running iOS 17 is a straightforward process. Head to the “Settings” app, tap “Safari,” and select “Advanced.” There you will find the JavaScript setting. Just switch it on, and voilà, JavaScript is now enabled on your iPhone.

After you complete this action, your mobile browser will be able to run JavaScript, which will greatly enhance your web browsing experience. Many websites use JavaScript for interactive features, so enabling it is crucial for a fully functional internet experience.

You can also watch this video about how to enable JavaScript on iPhone for additional info.

Introduction

So, you’ve just updated your iPhone to the latest iOS 17, and you’re excited to explore all the new features. But wait, you’re trying to play a game or use a feature on a website, and it’s not working. You scratch your head, wondering what could be wrong. Then it hits you – you need to enable JavaScript. But why is this important?

JavaScript is a programming language that makes web pages interactive. It’s like the secret sauce that adds functionality to websites – from refreshing your social media feed to playing online games, it’s the behind-the-scenes worker that makes it all happen. Without it, you’d be stuck in a world of static and boring web pages. And since we all use our iPhones for pretty much everything these days, from work to entertainment, having JavaScript enabled is a must. This tutorial is relevant to anyone who wants to make the most out of their iPhone’s browsing capabilities. Whether you’re a student, a professional, or just someone who loves to surf the web, this one’s for you.

Step by Step Tutorial on Enabling JavaScript on iOS 17

Before we jump into the steps, let’s understand what we’re trying to achieve here. By enabling JavaScript, you’re allowing your iPhone to execute JavaScript code on websites you visit, which will provide a richer browsing experience. Let’s get started!

Step 1: Open the Settings App

Open the “Settings” app on your iPhone.

The “Settings” app is your gateway to customizing your iPhone experience. It’s where you can adjust everything from your wallpaper to your privacy settings.

Step 2: Scroll and Tap on Safari

Scroll down and tap on “Safari,” which is Apple’s built-in web browser.

Safari is optimized for iOS, which means it’s designed to work seamlessly with your iPhone’s hardware and software.

Step 3: Tap on Advanced

Once in Safari settings, scroll down to the bottom and tap on “Advanced.”

The “Advanced” section is where you’ll find settings that are more technical, such as website data and debugging options.

Step 4: Toggle JavaScript On

In the “Advanced” section, you’ll see the “JavaScript” option. Toggle the switch to the right to turn it on.

When the switch is green, it means JavaScript is enabled. If it’s gray, that means it’s turned off.

Additional Information

Now that you’ve got JavaScript up and running on your iPhone, you might want to consider a few extra details. For starters, remember that not all websites are created equal. Some might not be optimized for mobile browsers, even with JavaScript enabled. Also, keep in mind that while JavaScript can make websites more interactive, it can also make them slower to load – especially if you’re on a slower internet connection.

If you’re concerned about security, you might want to be selective about where you enable JavaScript. Some websites might try to run harmful scripts, so it’s good to stay vigilant. You can always disable JavaScript for specific websites in the Safari settings under “Content Blockers.”

Remember, enabling JavaScript on iOS 17 should improve your web browsing experience, but it’s also important to use it wisely.

• Open the “Settings” app.
• Tap on “Safari.”
• Tap on “Advanced.”
• Toggle JavaScript to “On.”

How To Enable JavaScript In Your Browser

Every developer knows the significance of JavaScript in web functionality. This article offers a clear guide on enabling JavaScript in various browsers, coupled with best practices and troubleshooting tips. A must-read for those keen on refining their web development skills.

💡 KEY INSIGHTS

• Disabling JavaScript can increase browsing security by preventing malicious scripts, but may also limit functionality on modern, interactive websites.
• Most browsers allow JavaScript to be disabled via their settings or options menu , though the exact path varies based on the browser's interface and version.
• Advanced users can use browser extensions like NoScript or ScriptSafe for more granular control, selectively enabling or disabling JavaScript on specific sites.
• Disabling JavaScript improves page load times and performance on resource-heavy websites, but may render some web applications unusable.

JavaScript is a fundamental tool in web development, enhancing user experiences and enabling interactive web features. While it's often enabled by default in most browsers, there are instances when it might be turned off. Let's explore the steps to ensure it's activated and ready for your projects.

Understanding The Need To Enable JavaScript

Checking if javascript is enabled, steps to enable javascript in different browsers, troubleshooting common issues, best practices after enabling javascript, frequently asked questions.

JavaScript is the powerhouse behind interactive web content . It transforms static web pages into vibrant, responsive platforms. Whether it's an animation that captures attention or real-time data updates, JavaScript is the unsung hero making it all possible.

The Role Of JavaScript

Dynamic content display, real-time form validation, interactive elements.

JavaScript is not just another coding language; it's the lifeblood of modern web interactivity. It acts as the bridge between static content and dynamic user experiences. With JavaScript, web pages become more than just information displays; they turn into interactive platforms that can adjust, react, and evolve based on user interactions. It ensures that web pages can provide immediate feedback, adapt to user choices, and offer tailored experiences without the need to constantly reload or navigate to new pages. In a digital age where user experience is paramount, JavaScript's role in enhancing this experience cannot be overstated.

Consider a scenario where content changes based on user selections:

JavaScript shines in its ability to validate user inputs instantly:

Elements like dropdowns, tabs, and pop-up modals are made interactive through JavaScript:

In the grand scheme of web browsing, enabling JavaScript is like turning on the lights in a room. It illuminates features, enhances interactivity, and ensures a seamless user experience.

Ensuring that JavaScript is active in your browser is pivotal. A disabled JavaScript can lead to web pages not functioning as intended, resulting in a compromised user experience.

Quick JavaScript Test

Using browser developer tools, common indicators and testing.

A basic script can provide immediate feedback on JavaScript's status:

Modern browsers come equipped with developer tools, which can be instrumental in checking JavaScript's status. Access your browser's developer tools (typically F12 or right-click and select "Inspect"), head over to the Console tab, and input console.log("JavaScript is functioning"); and hit Enter. If "JavaScript is functioning" appears in the console, it indicates that JavaScript is operational.

While direct methods are reliable, there are indirect signs hinting that JavaScript might be off, such as static behavior, lack of interactivity, and content issues. You can also create a button on a web page to test JavaScript:

In conclusion, ensuring JavaScript's activation is crucial for a seamless web experience. It's the gateway to a host of interactive features and guarantees that web pages operate as designed.

Enabling JavaScript is essential for a dynamic and interactive web experience. The process to enable JavaScript varies slightly across different browsers. Here's a step-by-step guide for the most popular ones:

Google Chrome

Mozilla firefox, microsoft edge.

• Open Chrome and click on the three vertical dots in the top right corner.
• Navigate to Settings .
• Scroll down and click on Advanced .
• Under the Privacy and security section, click on Site settings .
• Find and click on JavaScript .
• Toggle the switch to Allowed .

• Launch Firefox and click on the three horizontal lines in the top right corner.
• Select Options .
• Click on Privacy & Security on the left sidebar.
• Scroll down to the Permissions section and click on Settings next to Block new requests asking to allow JavaScript .
• Ensure that the desired websites are not listed, or if they are, change the status to Allow .
• Open Edge and click on the three horizontal dots in the top right corner.
• Choose Settings .
• Scroll down and select Site permissions .
• Click on JavaScript .
• Use the toggle to switch JavaScript to Allowed .
• Launch Safari and click on Safari in the top left corner.
• Choose Preferences .
• Go to the Security tab.
• Ensure the box next to Enable JavaScript is checked.
• Open Opera and click on the Opera logo in the top left corner.
• In the left sidebar, click on Advanced and then Privacy & security .
• Under Site settings , click on JavaScript .
• Toggle the switch to ensure JavaScript is Allowed .

By following these steps for each browser and running the associated scripts, you can confirm that JavaScript is enabled and functioning correctly.

While enabling JavaScript in browsers is generally a straightforward process, you might sometimes face challenges. Here are some common issues related to enabling JavaScript and their solutions:

JavaScript Option Not Found

Javascript still not working after enabling, browser extensions blocking javascript, pop-up blockers preventing javascript alerts, javascript enabled but some features still don't work.

In some browser versions or settings, the option to enable JavaScript might be hidden or located in a different menu.

Even after enabling, some websites might not recognize that JavaScript is active.

Some browser extensions, especially ad blockers or privacy-focused add-ons, might block JavaScript.

JavaScript alerts might be blocked by pop-up blockers, making it seem like JavaScript isn't working.

Some websites might use outdated JavaScript methods or have conflicts with other scripts.

By addressing these common challenges, you can ensure that JavaScript is not only enabled but also functioning optimally in your browser.

Once you've enabled JavaScript, it's essential to follow best practices to ensure optimal performance, security, and user experience. Here are some guidelines to consider:

Use Strict Mode

Regularly test across browsers, optimize performance, handle errors gracefully, keep security in mind.

JavaScript's "strict mode" helps catch common coding errors and prevents the use of potentially problematic features.

Avoid Global Variables

Using global variables can lead to unexpected behavior and conflicts, especially in larger applications.

Different browsers might interpret JavaScript slightly differently. Regular testing ensures compatibility.

Avoid using expensive operations, especially in loops, to ensure your scripts run efficiently.

Errors are inevitable. Use try-catch blocks to handle them without breaking your application.

Always validate and sanitize user input to prevent security vulnerabilities like cross-site scripting (XSS).

By adhering to these best practices, you'll ensure that your JavaScript code is efficient, secure, and provides a consistent user experience across different platforms and devices.

Are there any security concerns with enabling JavaScript?

While JavaScript is essential for many web functionalities, it can also be exploited for malicious purposes. It's crucial to keep your browser updated and use reputable security software. If you're concerned about a specific site, consider using browser settings or extensions that allow you to enable JavaScript only for trusted websites.

How can I tell if a website is using JavaScript?

Many modern websites use JavaScript for various functionalities. If you see dynamic content updates, animations, or interactive features, it's likely powered by JavaScript. Additionally, you can right-click on a webpage, select "Inspect" or "View Page Source", and look for <script> tags or .js files.

What is the difference between synchronous and asynchronous JavaScript, and how does it affect page loading?

Synchronous JavaScript blocks the browser until it finishes executing, potentially delaying page rendering. Asynchronous JavaScript, on the other hand, allows the browser to continue processing other tasks while the script runs in the background. Using asynchronous scripts or techniques like AJAX can improve page load times and user experience.

How does JavaScript handle concurrency, and what's the role of the Event Loop?

JavaScript is single-threaded, meaning it processes one task at a time. The Event Loop handles this by continuously checking the message queue for pending tasks. When the JavaScript engine is free, the Event Loop dequeues a message and executes it. This mechanism allows JavaScript to handle asynchronous operations without multi-threading.

How does Cross-Origin Resource Sharing (CORS) impact JavaScript requests?

CORS is a security feature implemented by web browsers to control requests to a different domain than the one that served the web page. For security reasons, web browsers restrict web pages from making requests to a different domain. However, with CORS, servers can specify who can access their assets, allowing for cross-domain AJAX requests in JavaScript.

How Apple made Safari about 60% faster in the last 6 months

A month ago, we told you about the release of Speedometer 3.0 , a new web performance testing benchmark that aims to provide a more fair and representative measure of how a web browser performs at modern web tasks. Unlike earlier versions of Speedometer, which were made more or less by Apple’s WebKit team, version 3.0 is made in a collaboration between Apple, Google, Microsoft, and Mozilla with a new governance model to agree upon what tests are important representations of the modern web.

In other words, it’s probably the most “fair” and up-to-date measurement of web browser performance we have right now.

WebKit is the rendering engine used by Safari and provided to Apple developers who wish to use web rendering within their apps. It’s required to be used by every browser on iOS or iPadOS except for those inside the EU. Apple’s WebKit development team published a blog post detailing how they used Speedometer 3.0 as a guide to optimize performance from Safari 17 (released in September 2023) and Safari 17.4 (released in March 2024).

Over those six months, a lot of small incremental improvements made a big difference. As the blog post summarizes:

With all these optimizations and dozens more, we were able to improve the overall Speedometer 3.0 score by ~60% between Safari 17.0 and Safari 17.4. Even though individual progressions were often less than 1%, over time, they all stacked up together to make a big difference. Because some of these optimizations also benefited Speedometer 2.1, Safari 17.4 is also ~13% faster than Safari 17.0 on Speedometer 2.1.

Some of those improvements include things like batching compositing layer updates, increasing cache size on macOS, improving inline and SVG layout, and more. Many of these improvements are minor, resulting in just a few percentage points here or there, or targeting very specific parts of web performance. But multiple small improvements compounding over time made for a much faster browser.

This doesn’t mean Safari is much faster than other Mac browsers, though. When we tested Speedomenter 3.0 last month , we were running Safari 17.4 and found it to be the fastest browser but only by a very small margin. Edge still had some catching up to do, but Chrome and Firefox are both just behind Safari’s Speedometer score.
