“How do I enable JavaScript in my browser?”

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.

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
• Safari: Open Preferences/Settings → Security → check Enable JavaScript.⁵¹²
• Android Chrome: Open Settings → Site settings → JavaScript → turn it on.¹⁷
• iPhone/iPad: JavaScript is usually on by default in Chrome, and in Safari you can check Settings > Safari > Advanced and turn JavaScript on if needed.⁷⁶

If a website still does not work after enabling it, reload the page and check whether an extension, tracking protection setting, or site-specific permission is blocking scripts.²³⁹

Here are the step-by-step instructions for enabling JavaScript in the most popular web browsers:

Google Chrome

Desktop (Windows / Mac)

• 1.Click the three vertical dots (menu) in the top-right corner and select Settings.

• 2.Scroll down and tap Safari (or Apps > Safari on iOS 18+).
• 3.Scroll to the very bottom and tap Advanced.
• 4.Toggle the switch next to JavaScript to On (green).

Microsoft Edge

• 1.Click the three horizontal dots in the top-right corner and select Settings.
• 2.In the left sidebar, click Cookies and site permissions.
• 3.Under the All permissions list, click JavaScript.
• 4.Toggle the switch next to Allowed (recommended) to the right (On).

Mozilla Firefox

Firefox has JavaScript enabled by default and does not show it in standard settings.

• 1.In the address bar, type about:config and press Enter.
• 2.Click Accept the Risk and Continue.
• 3.In the search bar at the top, type javascript.enabled.
• 4.If the value says false, double-click it (or click the Toggle button on the right) so it changes to true.

• 1.Click the three horizontal lines in the top-right corner and select Settings.
• 2.Click Privacy and security > Site and Shields Settings.
• 3.Under Content, click JavaScript.
• 4.Select Sites can use JavaScript.

*Tip: After enabling JavaScript, make sure to refresh/reload any open web pages for the changes to take effect.*

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.

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

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
