“What are the steps for turning on JavaScript?”

JavaScript is usually enabled by default. If a website says it’s off, try the steps for your browser:

• Chrome (computer): Select ⋮ → Settings → Privacy and security → Site settings → JavaScript → choose Sites can use JavaScript. (support.google.com)
• Safari (Mac): Choose Safari → Settings → Security → check Enable JavaScript. (support.apple.com)
• Firefox: JavaScript is normally enabled already. If a setting or extension has disabled it, check the extension’s settings; advanced users can check javascript.enabled at about:config. (support.mozilla.org)

If you tell me your browser and device—such as Chrome on Android or Safari on iPhone—I can give you the exact steps.

To turn on JavaScript, open your browser settings, go to the JavaScript permission or site settings, and switch it to allowed / sites can use JavaScript.¹²⁴

Common steps by browser are:

• Chrome: Open Settings → Privacy and security → Site settings → JavaScript → select Sites can use JavaScript.¹²³
• Microsoft Edge: Open Settings → Cookies and site permissions → JavaScript → turn it Allowed.²⁴
• Firefox: Type about:config in the address bar, search for javascript.enabled, and set it to true.⁴⁹
• Safari: Open Preferences/Settings → Security and check Enable JavaScript.⁴¹⁷

If JavaScript is already on but a site still says it is disabled, refresh the page or restart the browser.²⁴

How to Turn On JavaScript

JavaScript is required for many websites to work properly — without it, you may be unable to stream audio and video or use other interactive features help.bbc.com. Here's how to enable it in the most common browsers.

Google Chrome (desktop)

• 1.Open Chrome and click the three-dot menu in the top right, then Settings.
• 2.Click Privacy and security.
• 3.Click Site settings.
• 4.Under "Content," click JavaScript.
• 5.Select Sites can use JavaScript as the default behavior.

From this screen you can also block JavaScript by default and then allow only specific sites you choose support.google.com, google.com.

Chrome on Android

• 1.Open Chrome and tap More > Settings.
• 2.Under "Advanced," tap Site settings > JavaScript.
• 3.Turn JavaScript on support.google.com.

Chrome on iPhone and iPad

JavaScript is turned on by default, so no action is usually needed support.google.com.

Microsoft Edge

• 1.Click the three dots in the upper-right corner and select Settings.
• 2.Select Cookies and site permissions from the left-hand menu.
• 3.Under "All permissions," select JavaScript.
• 4.Toggle Allowed to the right so the toggle turns blue.
• 5.Close the settings window and refresh your browser help.bbc.com.

Mozilla Firefox

• 1.Type about:config in the address bar and press Return.
• 2.Click Accept the Risk and Continue to proceed.
• 3.Search for the javascript.enabled preference.
• 4.Click the Toggle (or Reset) button to set it to true google.com, help.bbc.com.

Safari on Mac

• 1.Launch Safari, then from the top menu click Safari > Preferences.
• 2.Click the Security icon.
• 3.In the "Web content" section, check the Enable JavaScript checkbox.
• 4.Close the window help.bbc.com, google.com.

Safari on iPhone and iPad

• 1.From the Home screen, go to Settings > Safari.
• 2.Tap Advanced (you may need to scroll down).
• 3.Tap the JavaScript switch to turn it on help.bbc.com.

Other browsers

If you use a supported browser other than those above — such as Opera — check its support page for instructions, since the exact menu names can differ support.google.com.

Troubleshooting tips

• Already enabled but not working? Try refreshing the page or clearing your browser cache help.bbc.com.
• Settings changed unexpectedly? Browser upgrades, security software, or patches can change your JavaScript setting, so it's worth confirming it's still allowed support.google.com.
• "Prompt" mode: Some browsers let you set JavaScript to "Prompt," which shows a warning when JavaScript is required and gives you the option to allow the content to load support.google.com.

Here's how to turn on JavaScript in the most common browsers, based on current 2026 settings:

Google Chrome (Desktop)

On a computer, open Chrome, click More, then go to Settings, Privacy and security, Site settings, Content, and JavaScript. Under Default behavior, select Sites can use JavaScript. This same path works on Windows, Mac, Linux, and ChromeOS.

Shortcut: You can skip the menus by pasting chrome://settings/content/javascript into the address bar and pressing Enter to jump straight to this page. Just remember to reload any open tabs afterward.

Chrome on Android: open Chrome, tap More, then tap Settings, Advanced, Site settings, and JavaScript, then turn on Javascript.

Microsoft Edge

Open Edge. Click Settings and more, then go to Settings, Privacy, search, and services, Site permissions, All permissions, and JavaScript. Make sure Allowed (recommended) is turned on.

If your Edge is managed by a workplace or school, note that an administrator can allow JavaScript with DefaultJavaScriptSetting, or allow specific sites with JavaScriptAllowedForUrls — both policies cover Edge on Windows, Mac, and Android, but not iPhone or iPad.

Mozilla Firefox

Good news — Firefox has JavaScript enabled by default. If it's somehow been turned off, you can re-enable it via the hidden config page:

• 1.Open Firefox and in the URL address bar type about:config and press Enter.
• 2.You'll see a warning — click "Accept the Risk and Continue."
• 3.In the search bar at the top, type javascript.enabled
• 4.Click the toggle option next to "false" and it will change to "true," enabling JavaScript

Safari

On Mac: open Safari, go to Settings, choose Security, and then select Enable JavaScript.

On iPhone/iPad: open Settings, tap Apps, choose Safari, open Advanced, then turn on JavaScript.

Quick tip: Most browsers have JavaScript enabled out of the box. If a website tells you it's disabled, it's usually because it was switched off earlier, by a corporate policy, or by a privacy extension. Let me know which specific browser or device you're using if you'd like more tailored instructions!

I'll search for current instructions to enable JavaScript in Chrome, Firefox, Safari, and Edge.

I've found general steps; now I'll look up the official documentation for each browser.

I'll open the official support pages to gather the exact steps for citations.

I still need the iPhone steps, so I'll search for Apple's iOS Safari instructions.

I'll open Apple's official troubleshooting guide to confirm the iPhone steps.
