How to Enable JavaScript on DuckDuckGo

The DuckDuckGo browser is available on iPhone, iPad, Android, macOS, and Windows, with JavaScript enabled by default. A blank page can result from site code, Web Tracking Protections, a content blocker, VPN or DNS filtering, or an app defect; do not assume the cause is an operating-system JavaScript switch.

This guide records current documented limitations across DuckDuckGo platforms. It publishes no global JavaScript control for iOS/iPadOS or Android because current vendor documentation reviewed here does not support one, and it treats Web Tracking Protections as distinct from disabling all JavaScript.

Enable JavaScript on DuckDuckGo for iPhone and iPad

JavaScript is enabled by default in DuckDuckGo on iPhone and iPad. This guide has no verified browser-specific JavaScript switch to give you for the current DuckDuckGo iOS/iPadOS app. Apple documents Settings → Apps → Safari → Advanced → JavaScript as a Safari setting, not as a control for DuckDuckGo.

If a site still says JavaScript is disabled

Update DuckDuckGo and iOS/iPadOS to their current stable versions.
Close and reopen the affected tab, then try a new private tab.
Temporarily disable any content blocker, VPN, or DNS filter and reload. Those tools can block scripts without changing the browser's JavaScript engine.
Reload this page and use its JavaScript status message to test actual execution.

If the problem remains, record the exact DuckDuckGo and iOS/iPadOS versions before troubleshooting further. This guide intentionally does not publish an unverified toggle path.

Enable JavaScript on DuckDuckGo for Android

JavaScript is enabled by default in DuckDuckGo on Android. Current DuckDuckGo documentation describes Web Tracking Protections but does not document a global JavaScript toggle for DuckDuckGo on Android. Do not look for an unverified control under Accessibility or Site Permissions.

If a site is not working

Update DuckDuckGo and Android, then reload the page in a new tab.
Open the site's Privacy Dashboard and temporarily disable protections for that site as a diagnostic. This changes DuckDuckGo protections; it is not a global JavaScript switch.
Temporarily disable VPN or DNS filtering and test again.
Reload this page and check the JavaScript status message.

The DuckDuckGo browser on macOS

JavaScript is enabled by default in DuckDuckGo on macOS. The current official help reviewed for this guide does not document a global JavaScript on/off switch. Check DuckDuckGo's current help for your exact app build before assuming that an undocumented setting exists or will remain absent.

The DuckDuckGo browser on Windows

JavaScript is enabled by default in DuckDuckGo on Windows. The current official help reviewed for this guide does not document a global JavaScript on/off switch. Check DuckDuckGo's current help for your exact app build before assuming that an undocumented setting exists or will remain absent.

How to verify JavaScript is now on in the DuckDuckGo browser

The clearest test:

Open a new tab and visit any JavaScript-detection page (this site has one).
If the page reports JavaScript is enabled, you are done.

You can also confirm via Web Inspector on the macOS app:

Press Cmd + Option + I on macOS.
Click the Console tab.
Type 1+1 and press Enter. If the console returns 2, JavaScript is running.

How to disable JavaScript on the DuckDuckGo browser

If you need the opposite, see our guide: How to Disable JavaScript on DuckDuckGo. It explains the documented limitations on each platform and avoids unverified iOS or Android toggle paths.

Does current DuckDuckGo documentation show an iPhone JavaScript setting?

Current DuckDuckGo documentation reviewed here does not document a DuckDuckGo-specific global JavaScript switch on iOS or iPadOS. Apple documents Settings -> Apps -> Safari -> Advanced -> JavaScript as a Safari setting, so this guide does not present that path as a DuckDuckGo control. If scripts appear blocked, check Web Tracking Protections, content blockers, VPN or DNS filtering, and the exact app and OS versions.

Does DuckDuckGo's tracker blocker disable JavaScript?

DuckDuckGo's Web Tracking Protections can block selected third-party tracking requests and scripts that match its protection lists. They do not disable all JavaScript and do not guarantee that every first-party interaction remains unaffected. If one site breaks, use the Privacy Dashboard only as a temporary diagnostic, reload, and restore your preferred protection setting. Record the exact app version rather than inferring a global JavaScript toggle.

Does current DuckDuckGo help document a Mac or Windows JavaScript toggle?

Current DuckDuckGo help reviewed here does not document a global JavaScript switch in the macOS or Windows apps. Check the help for the exact app build rather than treating that documentation gap as permanent. For no-JavaScript testing, use a browser or DevTools workflow with a documented control. This guide likewise does not present Safari's setting as a DuckDuckGo control on iOS or iPadOS.
