There’s now a command menu built into DevTools that makes it easier to disable JavaScript. This has been around as of April 2016 or so.

Use the Enable JavaScript command when you want to turn it back on.

How to Disable JavaScript in Almost Any Browser

Updated: August 7, 2022

In 2022 I think it’s still important as a web developer to test your how your websites look and function when users disable JavaScript in their browser. Developing in this way used to be a cornerstone of Progressive Enhancement and can be handy on both desktop or mobile.

I still find myself wanting disabling JavaScript on pages I visit. Sometimes it’s to test a page I’m working on, but in other instances it’s simply to visit a web page that’s not functioning correctly and I want to see if JavaScript is the culprit.

So here’s a list (that I’ll keep updated) showing you how to disable JavaScript in different browsers on desktop and mobile.

Disable JavaScript in Chrome

In Google Chrome, I’m sure this setting has changed places a few times over the years, but you can always do a quick keyword search to find it.

As mentioned, it’s not always easy to remember exactly where this is so if you forget, just type “JavaScript” in the “Search settings” box at the top when the settings page first appears. The search will indicate that you should click on the “Site settings” option and then from there the “JavaScript” feature will be highlighted.

Disable JavaScript in Firefox

Firefox has a completely different way of doing this. If you go into the settings page via the “Tools” menu, you’ll see a search option. But typing “JavaScript” into that search field doesn’t bring up anything.

Disabling JavaScript in Firefox is done as follows:

You can also filter it down even more by typing “javascript.enabled” but it’s basically the same thing, it just shows you other JavaScript-related preferences.

Disable JavaScript in Microsoft Edge

The Edge browser is now built on Chromium, so you’ll find this is similar to disabling JavaScript in Chrome. You can do a search for the keyword on the settings page, or follow these steps:

From there, similar to other browsers, you can even enable or disable JavaScript on a per-site basis if necessary.

Disable JavaScript in Brave Browser

Brave is another Chromium-based browser that’s gained popularity over the last few years because of its privacy features and Brave Rewards program. In Brave you can likewise do a search for the JavaScript setting, or follow these steps:

For some reason, all these Chromium browsers spell “JavaScript” wrong in this area of the settings, using the casing “Javascript”. You’d think Brave, the browser that was founded by the guy who invented JavaScript would correct that – but apparently not.

Disable JavaScript in Opera

Opera is another browser that has moved over to Chromium, but the options and settings are a little different from the others I’ve described above.

Again, once you’re on the Settings page, you can do a search if you forget where the option is.

Disable JavaScript in Vivaldi

Vivaldi is a relatively new browser launched in 2016 that was co-founded by a former CEO of Opera Software, so its features are similar to pre-Chromium Opera, though it also uses Chromium as its base.

Vivaldi is a little confusing, because there doesn’t seem to be a way to access the full settings from the browser UI. For example, there’s a cog icon in the bottom left corner, and you can also access “Settings…” by clicking the Vivaldi logo in the top left corner. But neither of these can access the JavaSript setting.

To disable JavaScript in Vivaldi, do the following:

What’s strange is if you type “vivaldi://settings/content/javascript” you won’t get the same screen. So it seems like using “chrome://” as the URL’s protocol forces Vivaldi to bring up the Chromium-based settings that aren’t directly accessible through the browser UI. As you can see in the screenshot, the URL will still redirect to “vivaldi://” but you have to type “chrome://” to get this settings page.

That being said, since this is a Chromium-based browser that includes the same DevTools as Chrome, Brave, Edge, etc., you can also disable JavScript as follows:

Disable JavaScript in DevTools in Chromium-based Browsers

In addition to the steps listed above for various Chromium-based browsers, if you’re regularly inside your browser’s developer tools, you can disable JavaScript as follows:

For a quicker way to do this, you can do the following inside DevTools:

You can also open the command palette by clicking the three-dots icon next to the cog icon, and choosing the “Run command” option. These options should be more or less the same on Chrome, Edge, Opera, and Brave.

Disable JavaScript in Firefox Developer Tools

In Firefox’s developer tools, you can use the following steps:

Disable JavaScript in Safari Desktop on Mac

The Safari browser for desktop is no longer available for Windows machines, but you can disable JavaScript on Safari on MacOS as follows:

I did not try this on the latest version of Safari, but I’m assuming it’s the same basic steps.

Disable JavaScript in Safari for iOS

On an iPhone, iPad, or other iOS-based device, you can disable JavaScript as follows:

Disable JavaScript in Chrome for iOS

It seems as though there was a way to do this in the past, but from what I can tell, there is no longer a setting that allows you to disable JavaScript in Chrome on iOS.

You can find website-related settings using the following steps:

According to some websites, the option used to be there, but now I only see “Block Pop-ups” and “Default apps”, neither of which leads to a JavaScript setting.

Disable JavaScript in Internet Explorer

If you must for some ungodly reason use IE11 or an older version of Internet Explorer, you can disable JavaScript as follows:

As a side point, my website looks atrocious in IE11 even with JavaScript enabled, which I assume is true of many websites that now use features like Flexbox and Grid for layout.

Disable JavaScript in Tor Browser

I don’t use the Tor browser, but I have it installed and disabling JavaScript in Tor is more or less similar to how you do it in Chromium-based browsers.

As you can see, this isn’t an option that is specifically for JavaScript but for a number of features that can cause privacy or security concerns.

Disable JavaScript in Chrome for Android

I don’t use Android, so this is based on what other websites say, but it looks to be very similar to other Chrome browsers. You can disable JavaScript on Android using the following steps:

Disable JavaScript in Opera Mobile or Opera Mini

The mobile version of Opera works similarly to other mobile browsers. You can access the settings by clicking the hamburger menu in the bottom menu.

Unfortunately, from what I can tell, there doesn’t seem to be an option to disable JavaScript in this browser. There is an option to block ads, popups, and cookie dialogs, but nothing that’s specifically to disable JavaScript.

As for Opera Mini, the old mobile browser that hasn’t been updated in a few years, technically this browser doesn’t run JavaScript on the client. Opera Mini serves static pages that are rendered on a proxy server. This means any JavaScript on the page will run on the proxy server, then you’ll get a static page with links rendered in the viewport.

Disable JavaScript in Android Browser

You can disable JavaScript on the generic browser that comes installed on Android phones as follows:

These steps might differ a little depending on the age of your Android phone.

Disable JavaScript in Samsung Internet Browser for Android

The Samsung Internet browser that comes installed on Samsung Galaxy devices has about 2-3% usage worldwide. You can disable JavaScript in Samsung Internet as follows:

Disable JavaScript in DuckDuckGo Privacy Browser

DuckDuckGo, well-known for its privacy-focused search engine, has an iOS and Android app called DuckDuckGo Privacy Browser that is also slated to include a desktop version soon.

While there is a “Settings” option accessible via the three-dot icon in the top-right area of the browser, I don’t see a way to disable JavaScript there or through the system settings for the app.

Disable JavaScript in UC Browser, QQ, Baidu, KaiOS, etc.

There are browsers popular in China, India, and other areas that I have not been able to find any definitive sources or do any testing of my own on how to disable JavaScript.

If you know how to disable JavaScript in any of these browsers, feel free to post a comment. Otherwise, in most cases you should be able to track down the settings by clicking the hamburger menu or a similar icon on the browser’s UI.

Disable JavaScript in Firefox Mobile

I installed Firefox Mobile on iOS and I cannot see a way to disable JavaScript in that browser, either through the browser’s “Settings” button or through the OS’s settings for that app.

There are options to block pop-up windows, block images, and some tracking protection settings but nothing specific to disable JavaScript in Firefox Mobile.

Anything I Missed?

If there’s a browser not listed here and you know how to disable JavaScript in it, feel free to let me know in the comments and I’ll add it to the post.

You can also post any corrections since I wasn’t able to test on all these devices.

Great round-up! I would add Firefox mobile to the list.
