How to Disable JavaScript on DuckDuckGo

Most people land on guides like this for the opposite reason: they want JavaScript on, not off. But there are real, legitimate reasons to switch JavaScript off in the DuckDuckGo browser. You may be defending against fingerprinting and tracking on top of DuckDuckGo's already-strong defaults, checking how a page degrades for users without JS, squeezing extra battery and CPU out of an older phone, or testing your own site without enabling JavaScript globally for everything else you visit.

How you do that depends entirely on which platform you are on - DuckDuckGo's iOS, Android, macOS, and Windows apps each handle JavaScript differently because of platform constraints (Apple's WebKit policy on iOS) and product decisions (no global toggle on desktop). This guide covers each path.

Before you disable: read this

With JavaScript turned off, expect the following:

  • Most single-page apps (Gmail, Google Docs, Slack, Notion, X/Twitter, Facebook, Instagram, online banking) will not load past a blank screen or a static fallback.
  • Login forms on many sites will fail silently because the submit button is wired up in JavaScript.
  • Search autocomplete, infinite scroll, video players, captchas, and "Add to cart" buttons will frequently break.
  • Many news sites and blogs work surprisingly well, because the body text is in the HTML.

DuckDuckGo's own tracker blocker already removes most of the privacy-hostile scripts from sites you visit, so disabling JavaScript on top is a stricter measure - useful for testing or for highly sensitive browsing, but not strictly necessary for everyday privacy.

Disable JavaScript on DuckDuckGo for iPhone and iPad

iOS browsers all run on Apple's WebKit engine. The JavaScript switch lives in the system Settings app and applies to DuckDuckGo, Safari, Chrome, Brave, and every other browser on the device.

Step 1: Open the iOS Settings app

Tap the gray Settings icon on the home screen or App Library.

Step 2: Tap Apps

Scroll down and tap Apps.

Step 3: Tap Safari

Inside Apps, tap Safari. This is the iOS gateway to the JavaScript switch for every browser on the device.

Step 4: Open Advanced

Scroll to the bottom of Safari's settings and tap Advanced.

Step 5: Switch JavaScript off

Tap the JavaScript toggle. It turns gray. JavaScript is now off across DuckDuckGo, Safari, Chrome, Brave, Edge, and every other iOS browser until you switch it back on.

Step 6: Verify in DuckDuckGo

Open the DuckDuckGo browser and reload a JavaScript-heavy site (Gmail or Twitter). It should fail to render the dynamic UI.

Disable JavaScript on DuckDuckGo for Android

The Android DuckDuckGo browser ships its own per-app rendering settings, including a JavaScript toggle.

Step 1: Open the DuckDuckGo browser

Tap the DuckDuckGo icon on your phone.

Step 2: Open the three-dot menu

Tap the three-dot menu in the top-right.

Step 3: Tap Settings

Scroll and tap Settings.

Step 4: Find the JavaScript control

In recent versions, JavaScript and other site-level settings sit under Accessibility or Site Permissions depending on your app build.

Step 5: Switch JavaScript off

Toggle JavaScript off. Reload any open tab.

The DuckDuckGo browser on macOS - no global toggle

The macOS DuckDuckGo browser does not currently expose a global JavaScript on/off toggle in its preferences. There is no in-app way to disable JavaScript for all sites at once. If you specifically need that capability on a Mac, your options are:

  • Switch to a Chromium-based browser for tasks where you want JavaScript off. Brave at brave://settings/content/javascript, Vivaldi at vivaldi://settings/content/javascript, and Chrome at chrome://settings/content/javascript all expose the global toggle and an allow-list workflow.
  • Use Safari instead if you want a WebKit browser with a JavaScript toggle. Safari has the toggle at Settings → Advanced → Show features for web developers → Develop → Disable JavaScript.
  • Trust the DuckDuckGo defaults. The built-in tracker blocker, Smart Encryption, and fingerprint randomisation already remove most of the privacy-hostile scripts you would otherwise want to disable JavaScript to block.

The DuckDuckGo browser on Windows - no global toggle

The Windows DuckDuckGo browser inherits the same design choice as the macOS app: there is no global JavaScript on/off toggle. JavaScript is always on, with the tracker blocker handling privacy.

If you need a global JavaScript toggle on Windows:

  • Chrome: chrome://settings/content/javascript
  • Edge: edge://settings/content/javascript
  • Brave: brave://settings/content/javascript
  • Vivaldi: vivaldi://settings/content/javascript
  • Firefox: about:config → javascript.enabled

How to verify JavaScript is now off in the DuckDuckGo browser

Settings can lie. Extensions can override them. The cleanest test:

  1. Open a new tab in the DuckDuckGo browser and visit any JavaScript-detection page.
  2. If the page reports JavaScript is disabled, the toggle is doing its job.
  3. Open a JS-heavy site like Gmail. It should fail to load the dynamic UI.

What to do if a site you need is now broken

The DuckDuckGo browser does not expose a per-site JavaScript allow-list the way Chrome and Brave do. If you have JavaScript disabled and a specific site is broken, your options are:

  1. Switch to a different browser for that one site. Open it in Safari, Chrome, or Brave - whichever still has JavaScript enabled.
  2. Re-enable JavaScript globally via the iOS Settings or Android in-app toggle, accept that everything has JS on, and rely on DuckDuckGo's tracker blocker for privacy.
  3. If you are on iOS, the system-wide nature of the WebKit toggle means re-enabling JavaScript turns it on for every browser at once. There is no DuckDuckGo-only allow-list.

Javascript is enabled in your web browser. If you disable JavaScript, this text will change.

F.A.Q

Can I disable JavaScript only inside the DuckDuckGo iPhone app?

No. Apple requires every iOS browser to use the system WebKit engine, and the JavaScript switch for that engine lives at the system level in iOS Settings -> Apps -> Safari -> Advanced. When you switch it off, JavaScript turns off across every browser on the device - DuckDuckGo, Safari, Chrome, Brave, Edge, and any others. There is no DuckDuckGo-specific JavaScript toggle inside the iOS app, and Apple does not currently allow third-party browsers to expose one.

Why does the DuckDuckGo Mac browser not have a way to disable JavaScript?

DuckDuckGo's macOS browser is built around the assumption that the tracker blocker handles privacy and JavaScript stays on so the web works as users expect. They have not added a global JavaScript toggle the way Chrome, Brave, Edge, and Vivaldi have. If you specifically need to disable JavaScript on a Mac, the practical options are to use Brave, Vivaldi, or Chrome (all of which have the toggle), or to use Safari, which exposes Disable JavaScript through its Develop menu after you enable Show features for web developers in Advanced settings.

Should I disable JavaScript in DuckDuckGo for privacy, or is the tracker blocker enough?

For most people, DuckDuckGo's tracker blocker is enough. It already removes the third-party analytics, ad-tech, and fingerprinting scripts that account for most of the privacy harm on the modern web, while leaving the site's own functionality intact. Disabling JavaScript globally is a stricter step that defends against scripts the tracker blocker has not seen yet - useful for highly sensitive browsing or for testing - but it also breaks most modern sites in obvious ways. The pragmatic recommendation is: trust the DuckDuckGo defaults for daily browsing, and reach for the JavaScript-off setting only when you need stronger isolation.
