It depends on your browser:

• Chrome (computer): Open ⋮ → Settings → Privacy and security → Site settings → JavaScript, then select Sites can use JavaScript. (support.google.com)
• Chrome (Android): Tap ⋮ → Settings → Site settings → JavaScript, then turn it on.
• Safari (iPhone/iPad): Open Settings → Apps → Safari → Advanced, then turn on JavaScript. On older iOS versions, go to Settings → Safari → Advanced.
• Safari (Mac): In Safari, choose Safari → Settings → Security, then check Enable JavaScript.
• Firefox: JavaScript is normally enabled by default. If a site still says it’s disabled, check whether an extension or privacy setting is blocking it. (support.mozilla.org)
• Microsoft Edge: Open ⋯ → Settings → Cookies and site permissions → JavaScript, then turn on Allowed.

After changing the setting, reload the page. If you tell me your browser and device, I can give you exact steps.

I'll look up the current steps for enabling JavaScript in the major browsers.

I've found the general locations — now I'll open the official guides to confirm the exact steps.

JavaScript is required for many features to work, and is normally on by default - you only need these steps if a site says it is off.

There is nothing to download - JavaScript is built into the browser. The setting is separate in each browser, so change it in the browser where the site is failing.

Quick shortcuts

Type this in the address bar:

• Chrome (desktop): chrome://settings/content/javascript
• Edge (desktop): edge://settings/content/javascript
• Firefox (desktop): about:config → javascript.enabled = true

Google Chrome - desktop

• 1.In Chrome, click More > Settings.
• 2.Click Privacy and Security.
• 3.Click Site Settings.
• 4.Under Content, select JavaScript.
• 5.Select Sites can use JavaScript. Chrome saves automatically.

Google shows this as: Settings > Privacy and Security > Site Settings > JavaScript > Sites can use Javascript.

Close the Settings tab and reload the website. To update your settings, reload your browser.

Chrome - Android: Settings > Site settings > JavaScript.

Microsoft Edge

• 1.Open Edge and select Settings and more - the three dots in the top-right, or press Alt+F.
• 2.Select Settings.
• 3.Select Privacy, search, and services in the list of categories.
• 4.Select Site permissions, then All permissions.

In short: Settings > Privacy, search, and services > Site permissions > All permissions > JavaScript, and make sure Allowed (recommended) is on.

Then go back to the site tab and press F5 to reload it.

Mozilla Firefox

Firefox turns JavaScript on by default and has no switch for it in the normal Settings page. The only built-in control is in the Configuration Editor:

• 1.Type about:config in the Firefox address bar and press Enter.
• 2.Select Accept the Risk and Continue.
• 3.Type javascript.enabled in the search box.
• 4.Look at the value. true means JavaScript is on, which is the default.

• 6.Close the tab and reload the website.

Safari - Mac

On Mac, choose Safari > Settings > Security and select Enable JavaScript.

Many interactive websites need JavaScript to work.

Safari - iPhone / iPad

Open Settings > Apps > Safari > Advanced and turn on JavaScript.

To enable JavaScript, open your browser’s Settings and turn on JavaScript in the site permissions or content settings. In Chrome, for example, go to Settings > Privacy and security > Site settings > JavaScript and choose Sites can use JavaScript.²⁷

Here are the common steps by browser:

• Chrome: Open Settings → Privacy and security → Site settings → JavaScript → select Sites can use JavaScript.²⁷
• Microsoft Edge: Open Settings → Cookies and site permissions → JavaScript → turn on Allowed (recommended).¹²⁹
• Firefox: Type about:config in the address bar, accept the warning, search for javascript.enabled, and set it to true.⁵¹⁴

JavaScript is usually on by default, but if it's been disabled (or blocked by an extension), here's how to turn it back on for each major browser.

Chrome

On a computer:

• 1.Open Chrome and click the three-dot menu → Settings
• 2.Click Privacy and security → Site settings
• 3.Under "Content," click JavaScript
• 4.Select Sites can use JavaScript (support.google.com)

You can also go directly to chrome://settings/content/javascript. From that screen you can add specific sites you want to block or allow.

On Android: Tap the three-dot menu → Settings → Site settings → JavaScript, then turn it on (support.google.com).

On iPhone/iPad: JavaScript is on by default, so no action is usually needed (support.google.com).

Microsoft Edge

• 1.Click the More menu → Settings
• 2.Select Cookies and site permissions → JavaScript
• 3.Select Allowed (recommended) (google.com)

Or go straight to edge://settings/content/javascript (testyourbrowser.com).

Firefox

• 1.Type about:config in the address bar and press Enter
• 2.Click Accept the Risk and Continue
• 3.Find the javascript.enabled preference
• 4.Click the Toggle button to set it to true (google.com)

Note that Firefox doesn't have a normal per-site JavaScript toggle — it's a global setting (testyourbrowser.com).

Safari

On macOS:

• 1.Go to Safari → Settings (or Preferences) → Security
• 2.Check Enable JavaScript (testyourbrowser.com)

You may need to quit and reopen Safari afterward.

On iPhone/iPad:

• 1.Open the Settings app
• 2.Go to Safari → Advanced
• 3.Turn JavaScript on (testyourbrowser.com)

If the site still doesn't work

JavaScript being enabled globally doesn't always mean it's running — other things can block it:

• Per-site permissions (fastest fix): In Chrome/Edge, click the lock icon in the address bar, open Site settings, and set JavaScript to Allow (testyourbrowser.com).
• Extensions: Script blockers like NoScript or strict filter modes in uBlock Origin can make sites look broken. Test in Incognito/InPrivate, where extensions are off, to confirm (testyourbrowser.com).
• Tracking protection / content blockers: In Firefox, try setting Enhanced Tracking Protection to Standard; in Safari, turn off Content Blockers via the aA menu; in Brave, lower Shields for the site (testyourbrowser.com).
• Network or DNS blocking: Try the site on a mobile hotspot. If it works there, your router, DNS filter, or office proxy may be blocking a required script domain (testyourbrowser.com).

One thing to keep in mind: browser upgrades, security software, or patches can change your JavaScript setting without you realizing it, so it's worth double-checking if ads or media suddenly stop displaying (support.google.com).

Here's how to enable JavaScript in the most common browsers:

Google Chrome

• 1.Click the three-dot menu (⋮) in the top-right corner
• 2.Go to Settings → Privacy and security → Site Settings
• 3.Click on JavaScript (under "Content" or "Permissions")
• 4.Select Sites can use JavaScript (or toggle it on)

Mozilla Firefox

Firefox doesn't have a simple toggle in the standard settings menu, but you can enable it via:

• 1.Type about:config in the address bar and press Enter
• 2.Click "Accept the Risk and Continue" if prompted
• 3.Search for javascript.enabled
• 4.Make sure the value is set to true (double-click to toggle if it's false)

Safari (Mac)

• 1.Open Safari → Settings (or Preferences)
• 2.Go to the Security tab
• 3.Check the box for Enable JavaScript

On newer macOS versions, this may be under Settings → Advanced → Show features for web developers, then enable it from the Develop menu.

Microsoft Edge

• 1.Click the three-dot menu (⋯) in the top-right corner
• 2.Go to Settings → Cookies and site permissions
• 3.Click JavaScript
• 4.Toggle Allowed (recommended) on

Safari (iPhone/iPad)

• 1.Open Settings app (not the Safari app itself)
• 2.Scroll to Safari → Advanced
• 3.Toggle JavaScript on

Chrome (Android)

• 1.Open Chrome → tap the three-dot menu
• 2.Settings → Site settings
• 3.Tap JavaScript and toggle it on

Note: Menu layouts can shift slightly between browser versions, so if you don't see an exact match, look for Settings → Privacy/Security → Site/Content Settings, where JavaScript controls are almost always located. If you let me know which specific browser and device you're using, I can give more precise steps.

JavaScript is on by default in current browsers. If a site says it is disabled, turn it back on in settings, then reload the page. Also check that the site is not on a block list and that an extension or content blocker is not stopping scripts.

Google Chrome (Windows, Mac, Linux)

• 1.Open the three-dot menu and choose Settings.
• 2.Go to Privacy and security → Site settings.
• 3.Under Content, open JavaScript.
• 4.Select Sites can use JavaScript.
• 5.If the site is listed under Not allowed to use JavaScript, remove it.

Shortcut: paste chrome://settings/content/javascript into the address bar.

Chrome on Android: Menu → Settings → Site settings → JavaScript → turn it on.

Microsoft Edge

• 1.Open the three-dot menu and choose Settings.
• 2.Go to Cookies and site permissions → JavaScript.
• 3.Turn the toggle On (Allowed).

Shortcut: paste edge://settings/content/javascript into the address bar.

Mozilla Firefox

• 1.Type about:config in the address bar and press Enter.
• 2.Click Accept the Risk and Continue.
• 3.Search for javascript.enabled.
• 4.If it is false, click the toggle so it becomes true.
• 5.Reload the page.

Only change that preference. Extensions can still block scripts even when this is true.

Safari on Mac

• 1.With Safari open, choose Safari → Settings (or Preferences on older macOS).
• 2.Open the Security tab.
• 3.Check Enable JavaScript.

On some newer macOS versions, if you do not see the option, open Advanced and enable Show features for web developers, then return to Security.

Safari on iPhone or iPad

• 1.Open the Settings app.
• 2.Tap Apps → Safari (on iOS 17 and earlier, tap Safari directly in Settings).
• 3.Scroll down and tap Advanced.
• 4.Turn JavaScript on (green).
• 5.Fully close Safari and open it again, then reload the site.

If it still does not work

• Remove the site from any JavaScript block list in the settings above.
• Temporarily disable ad blockers, privacy extensions, or content blockers and reload.
• Try a private/incognito window to rule out an extension.
• Clear the site’s cached data, or try another browser.

Most sites need JavaScript for forms, menus, video, and sign-in. Leaving it enabled is normal for everyday browsing.

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

(After enabling JavaScript, be sure to reload any web pages you currently have open to apply the change.)

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.

JavaScript is required for many features to work.

Steps vary by browser:

1. Chrome - Computer

• 1.In the Chrome browser, click More > Settings.
• 2.In the Settings menu, click Privacy and Security.
• 3.Click Site Settings > JavaScript.
• 4.In the Default behavior section, select Sites can use JavaScript.

If you encounter a JavaScript error in Edge:

• 1.On the More menu (...), select Settings.
• 2.Select Privacy, search, and services < Site permissions < All permissions.
• 3.Select JavaScript to check if Allowed (recommended) is turned on.

3. Mozilla Firefox

By default, Firefox enables the use of JavaScript and requires no additional installation.

If it was disabled, check in Advanced Preferences:

Warning: These instructions are for experienced Firefox users. Changing settings in the Configuration Editor (about:config) can have serious effects on your browser’s stability, security and performance.

Only proceed if you are comfortable with advanced settings and understand the potential impacts.

• 1.Type about:config in the address bar and press Enter Return.
• 2.A warning page may appear. Click Accept the Risk and Continue to go to the about:configpage.
• 3.Find the javascript.enabled preference. It should be set to true by default.
• 4.If javascript.enabled is set to false, click the Toggle or Reset button to set it back to true.

4. Safari - Mac

• 1.To change these settings, choose Safari > Settings, then click Security.
• 2.From the Safari menu, select Settings > Security tab.
• 3.Click the Enable JavaScript check box.

This setting will Allow JavaScript, which websites use for buttons, forms, and other content.

• 1.Click Close and refresh the browser.

5. Safari - iPhone, iPad

Turn on JavaScript if it's not already on:

• 1.Go to Settings, then tap Apps.
• 2.Tap Safari.
• 3.Tap Advanced, then turn on JavaScript.

JavaScript is turned on by default in current browsers. If a site says it is off, use the steps below for your browser, then reload the page.

Google Chrome (computer)

• 1.Open the menu (three dots) and choose Settings.
• 2.Go to Privacy and security → Site settings.
• 3.Open JavaScript.
• 4.Select Sites can use JavaScript.

Shortcut: paste chrome://settings/content/javascript into the address bar.

On Android: menu → Settings → Site settings → JavaScript, then turn it on.

Microsoft Edge

• 1.Open the menu (three dots) and choose Settings.
• 2.Go to Cookies and site permissions (or Privacy, search, and services → Site permissions).
• 3.Open JavaScript.
• 4.Turn on Allowed (recommended).

Shortcut: paste edge://settings/content/javascript into the address bar.

Mozilla Firefox

• 1.Type about:config in the address bar and press Enter.
• 2.Accept the risk warning.
• 3.Search for javascript.enabled.
• 4.If it is false, click the toggle so it becomes true.

Safari on Mac

• 1.Open Safari → Settings (or Preferences on older macOS).
• 2.Open the Security tab.
• 3.Check Enable JavaScript.

On some recent macOS versions, if you do not see that checkbox, open the Advanced tab, turn on Show features for web developers, then return to Security and enable JavaScript.

Safari on iPhone or iPad

• 1.Open the Settings app.
• 2.Tap Apps → Safari (on older iOS, Safari is in the main Settings list).
• 3.Tap Advanced.
• 4.Turn JavaScript on (green).

If it is already on and a site still fails

• Disable content blockers or extensions such as NoScript, uBlock Origin (strict modes), or similar privacy tools, then reload.
• Check that the site is not listed under blocked/not allowed exceptions in the browser’s JavaScript settings.
• Try a private/incognito window or another browser to see whether an extension or profile setting is the cause.

JavaScript is usually enabled by default. The steps depend on your browser:

• Chrome (computer): ⋮ More → Settings → Privacy and security → Site settings → JavaScript → select Sites can use JavaScript. (support.google.com)
• Safari on Mac: Safari → Settings → Security → check Enable JavaScript. (support.apple.com)
• Firefox: JavaScript is normally on. If an extension or privacy add-on is blocking it, check that add-on’s settings; for an advanced check, enter about:config in the address bar and make sure javascript.enabled is true. (support.mozilla.org)

If you’re using a phone, tablet, or a different browser, tell me which one and I’ll give you the exact steps. If it’s a work- or school-managed device, an administrator may control the setting.

To unblock JavaScript, you usually need to change your browser’s site settings or disable any extension that is blocking scripts. In Chrome, for example, open Settings → Privacy and security → Site settings → JavaScript and choose Sites can use JavaScript; you can also allow JavaScript only for specific sites there.⁷⁸

If you use a different browser, the steps are similar:

• Firefox: open about:config, find javascript.enabled, and make sure it is set to true.²
• Edge / other Chromium browsers: go to Site settings or Cookies and site permissions, then JavaScript, and turn it Allowed.¹³¹⁵
• Mobile Chrome on Android: open Settings → Site settings → JavaScript and turn it on.⁷
• iPhone/iPad: JavaScript is typically on by default in iOS browsers, so if sites still complain, the issue is often an extension or content blocker rather than the browser setting itself.⁷

If JavaScript is already enabled but still blocked, check for privacy or content-blocking extensions such as NoScript, Ghostery, or similar tools, and either disable them or allow the site you want to use.²¹²

If you want, I can give you the exact steps for your browser and device.

I'll look up the current steps to enable JavaScript across major browsers.

To unblock JavaScript, you turn it on in your browser settings. Most interactive websites need JavaScript to work.

1. Google Chrome - Computer

• 1.Open Chrome > click the 3-dots More > Settings
• 2.Go to Privacy / Privacy and security > Content settings
• 3.Under Content, click the JavaScript option
• 4.Select Sites can use JavaScript / Allow all sites to run JavaScript (recommended) in the "JavaScript" section

Shortcut: paste chrome://settings/content/javascript into the address bar to open this page directly.

You can allow or block JavaScript for specific websites in Google Chrome.

2. Google Chrome - Android

JavaScript is Enabled by Default in Chrome. To check / turn it back on:

• 1.Open Chrome and tap the Menu icon (three vertical dots) in the top-right corner
• 2.Tap Settings
• 3.Tap Site Settings, then tap JavaScript
• 4.Move the slider to the right to turn JavaScript on

3. Safari - Mac

On Mac, choose Safari > Settings > Security and select Enable JavaScript.

In detail:

• 1.Click on Safari Menu and select Preferences…
• 2.In the Preferences window select the Security tab
• 3.In the Security tab section Web content mark the Enable JavaScript checkbox

4. Safari - iPhone / iPad

On iPhone or iPad, open Settings > Apps > Safari > Advanced and turn on JavaScript.

That is also described as: go to “Settings,” scroll down to “Safari,” tap on “Advanced,” and toggle the switch for “JavaScript” to the ON position.

5. Microsoft Edge

• 1.Open Edge and click on the three dots in the upper right corner
• 2.Go to: Edge > Settings > Cookies and site permissions > JavaScript > Allowed

Shortcut: paste edge://settings/content/javascript into the address bar to open this page directly.

Alternative path: Enter "edge://settings/content/javascript" in the address bar and make sure "Allow all sites to run JavaScript" is enabled.

6. Mozilla Firefox

Firefox does not expose a JavaScript switch in its normal Settings UI because it assumes JavaScript should always be on.

Firefox browser requires no additional installation. It enables the use of JavaScript, by default. If it does not, you can change it via the Firefox Configuration Editor (about:config page):

• 1.Type about:config in the address bar
• 2.In the search field, type javascript.enabled
• 3.Double click on the 'javascript.enabled' line to change the value from false to true

That is summarized as: about:config > javascript.enabled set to true.

If it still doesn't work

If enabling JavaScript doesn’t solve your problem, clear your cache, disable extensions, and update your browser.

Tell me which browser + device - e.g. Chrome on Windows, Safari on iPhone - and I can give you the exact taps.

Still Blocked? Check Extensions & Ad Blockers

If JavaScript is enabled in your browser settings but a site still warns that JavaScript is blocked:

• Ad blockers & script blockers: Extensions like uBlock Origin, AdBlock, or NoScript can block scripts from running. Try temporarily pausing the extension or whitelisting the site.
• Brave Browser Shields: If you use Brave, click the Brave Shield icon (lion logo) in the address bar and toggle shields down, or check if "Block Scripts" is turned on.
• Antivirus software: Some security suites (e.g., Avast, Norton, Bitdefender) have web-protection modules that block certain browser scripts.

Here's how to enable (unblock) JavaScript on common browsers and devices:

On Desktop

Google Chrome

• 1.Click the three-dot menu → Settings
• 2.Go to Privacy and security → Site settings
• 3.Click JavaScript
• 4.Select Sites can use JavaScript (or add the specific site to the "Allowed" list if it's blocked individually)

• 1.Type about:config in the address bar and press Enter
• 2.Accept the risk warning
• 3.Search for javascript.enabled
• 4.Make sure it's set to true (double-click to toggle if needed)

Microsoft Edge

• 1.Click the three-dot menu → Settings
• 2.Go to Cookies and site permissions → JavaScript
• 3.Toggle it On, and check the "Block" list to remove any sites you want to allow

Safari (Mac)

• 1.Open Safari → Settings (or Preferences)
• 2.Go to the Security tab (or Advanced tab on newer versions)

Additional Tips

• If JavaScript is already enabled globally but one site still won't run it, check if that specific site is on a "blocked" list in your browser's site settings and remove it.
• Browser extensions (like ad blockers, privacy tools, or "NoScript") can also block JavaScript even if the browser setting is on — check your installed extensions and disable or whitelist the site there.
• Some antivirus or parental control software can block JavaScript too, so check those settings if the browser-level fix doesn't work.

If you let me know which specific browser and device you're using, I can give you more precise, step-by-step instructions.

JavaScript is usually enabled by default, but if it’s blocked you can turn it back on in your browser’s site settings. The exact steps depend on your browser/device.

Chrome on computer

• 1.Open Chrome → three-dot menu → Settings
• 2.Go to Privacy and security → Site settings
• 3.Under Content, click JavaScript
• 4.Select Sites can use JavaScript — or allow only specific sites if you prefer. support.google.com

Chrome on Android

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

Samsung Internet

• 1.Open Samsung Internet → Tools → Settings
• 2.Tap Sites and downloads → Site permissions
• 3.Turn on Allow JavaScript. samsung.com

Chrome on Samsung devices

• 1.Open Chrome → More options (three dots) → Settings
• 2.Tap Site settings → JavaScript
• 3.Tap the switch to enable it. samsung.com

iPhone / iPad JavaScript is turned on by default for iPhone and iPad. support.google.com

Other browsers

• Microsoft Edge: More menu → Settings → Cookies and site permissions → JavaScript → Allowed. google.com
• Mozilla Firefox: Type about:config → Accept the Risk → find javascript.enabled → toggle to true. google.com
• Safari: Safari → Preferences → Security → check Enable JavaScript. google.com
• Opera: Settings → Advanced → Privacy & security → Site settings → JavaScript → turn on Allowed. google.com

If it still doesn’t work, browser upgrades, security software, or patches may have changed the setting, so confirm JavaScript is allowed again. Some browsers also have a Prompt setting — if an ad or page needs JavaScript, choose to allow it when prompted. support.google.com

On Samsung devices, you can also try checking software/app updates, confirming your internet connection, clearing cache/cookies, and running Device care → Optimize now. samsung.com

JavaScript is enabled by default in most browsers. If a site says it’s blocked, check browser settings first, then extensions or content blockers.

Google Chrome (computer)

• 1.Open Chrome and go to chrome://settings/content/javascript, or use the menu: Settings → Privacy and security → Site settings → JavaScript.
• 2.Select Sites can use JavaScript.
• 3.Reload the page.

On Android: Chrome menu → Settings → Site settings → JavaScript → turn it on.

Microsoft Edge

• 1.Go to edge://settings/content/javascript, or Settings → Cookies and site permissions → JavaScript.
• 2.Turn JavaScript On / Allowed.
• 3.Reload the page.

Mozilla Firefox

• 1.Type about:config in the address bar and continue past the warning.
• 2.Search for javascript.enabled.
• 3.Set it to true if it is false.
• 4.Reload the page.

Safari

Mac: Safari menu → Settings (or Preferences) → Security → check Enable JavaScript.

iPhone / iPad: Open the Settings app → Apps → Safari (on older iOS, Safari is listed directly) → Advanced → turn JavaScript on.

If it’s still blocked

• Extensions: Disable script blockers such as NoScript, uBlock Origin (in strict mode), or similar content blockers, then reload.
• Site exceptions: In Chrome/Edge JavaScript settings, remove the site from any “Not allowed” list, or add it to the allowed list.
• Cache: Clear the browser cache and try again, or test in a private/incognito window.
• Work or school devices: A policy or management profile may force JavaScript off. You may not be able to change that yourself.

Tell me your browser and device (for example, Chrome on Windows, or Safari on iPhone) if you want steps narrowed to that setup.
