“What's the best way to turn on JavaScript for a specific website?”

A good way depends on your browser. Quick steps for the main ones:

• Chrome (Windows/Mac/Android)
• Option A (fastest on the site): open the site, click the padlock/controls icon at the left of the address bar > Site settings > JavaScript > Allow, then reload. (support.google.com)
• Option B (from settings): Settings > Privacy and security > Site settings > JavaScript. Leave the global setting as “Don’t allow,” then add the site under Allow; or keep the global “Allowed” and add the site under Block/Allow as needed. (support.google.com)

• Microsoft Edge (Windows/Mac/Android)
• Settings > Cookies and site permissions > JavaScript. Use the Allow or Block lists to add just the site you want. In managed/enterprise setups there’s also a policy (JavaScriptAllowedForUrls) for per‑site allows. (support.microsoft.com)
• Note: Edge’s “Enhance your security” feature can restrict JavaScript/JIT on unfamiliar sites; adding a site exception or turning that feature off for a site also re‑enables JS there. (support.microsoft.com)

• Firefox (Windows/Mac/Linux)
• JavaScript is on by default and Mozilla doesn’t expose a simple per‑site JS toggle in normal settings. For per‑site control, use an extension such as NoScript or uBlock Origin’s per‑site “no‑scripting” switch. Changing advanced prefs (about:config) is possible but not recommended. (support.mozilla.org)

• Safari
• macOS: JavaScript is a single global toggle in Safari > Settings > Security (or Advanced, depending on version). Safari doesn’t offer a built‑in per‑site JS on/off switch. If JS is off globally, you’ll need to turn it on for all sites. (support.apple.com)
• iPhone/iPad: JavaScript is also a global toggle in Settings > Safari > Advanced. No per‑site switch. (athenahealth.com)

If you tell me your device and browser, I can tailor the exact clicks/taps for you and help troubleshoot if it still doesn’t work.

The easiest and most reliable way to turn on JavaScript for just one website (while keeping it off or controlled elsewhere) is through your browser's site-specific permissions, usually accessible right from the address bar. Here's how to do it in the most common browsers:

Google Chrome (recommended method — via address bar)

• 1.Go to the website in question.

2. Click the tune icon (sliders) or lock icon on the left side of the address bar.

3. Click Site settings.

4. Find JavaScript in the permissions list and change it from Block to Allow.

5. Reload the page.

Alternative (via Settings menu): Navigate to the JavaScript settings of Google Chrome, scroll down to the "Allowed to use JavaScript" section, click "Add," then type in the domain name or subdomain of the site you want to enable JavaScript on, and click "Add." This is useful if your global default is set to block JavaScript everywhere, since you can keep JavaScript enabled globally and only disable it for specific untrusted websites, or vice versa.

Chrome on Mobile (Android/iOS)

Click "Add Site Exception" in the same menu, then input the URL of the website that you want to allow to use JavaScript.

Microsoft Edge

Go to Settings, search for JavaScript and click on it, then click Allowed. You can also specify specific sites to enable or disable JavaScript.

Firefox

Firefox doesn't have a clean per-site toggle like Chrome — its JavaScript setting is global via about:config:

In the address bar, type about:config and press Enter, click "Accept the Risk and Continue," then in the search field type javascript.enabled, and click the Toggle icon on the far right.

This affects all sites, not just one. For per-site control in Firefox, you'd need an extension (similar to Chrome's extension option below).

Brave

Click Privacy and security → Site and Shields settings, scroll to Content and click JavaScript, select "Sites can use JavaScript," and if a single site is still broken, click the lion (Shields) icon and switch off "Block scripts" for that site.

Using an extension (any site, quickly, on demand)

If you frequently need to toggle JavaScript per-site, you can enable and disable JavaScript manually in Chrome, but it takes time, especially if you want the settings to apply only to a particular website — this is where an extension helps. A popular lightweight option is an extension that adds a one-click toggle in your toolbar for the current site only.

Bottom line: If you just need JavaScript on for one site right now, the fastest method in any Chromium-based browser (Chrome, Edge, Brave, Vivaldi) is: click the padlock/site-info icon in the address bar → Site settings → set JavaScript to Allow → reload the page. Firefox requires either the global about:config toggle or a browser extension for true per-site control.

Enabling JavaScript for a Single Site in Chrome

If JavaScript is working fine globally but blocked on one particular site, you don't need to touch your default settings — you can override the permission for just that site.

The quick method (per-site override)

• 1.Open Chrome and go to the website in question.
• 2.Click the tune icon (sliders) or lock icon to the left of the address bar.
• 3.Select Site settings.
• 4.Find JavaScript in the permissions list and change it from Block to Allow.
• 5.Reload the page — JavaScript will now run on that site only.

This is the approach recommended by enablejavascript.io, which notes that "previously saved site settings open" when you click the icon next to the web address, so you can change them without diving into Chrome's main settings menu at all.

The settings-menu method

Google's own documentation describes the same flow from the other direction:

• 1.On your computer, open Chrome.
• 2.Go to the site.
• 3.To the left of the web address, select View site information.
• 4.Select Site settings.
• 5.Change the permission setting.

Per support.google.com, your changes save automatically, and the site will use its own settings instead of your defaults. That same page also notes you can hit Reset permissions to undo your changes, and that Chrome removes permissions from sites you haven't used recently to protect your data.

Checking whether it's a site-level or global issue

The enablejavascript.io guide suggests a useful diagnostic: if another website still asks you to enable JavaScript after you've allowed this one, "check that site's permissions and any script-blocking extensions, then reload it." In other words:

• One site broken, others fine → site-level exception or an extension is blocking it.
• All sites broken → your global default has been switched to "Don't allow sites to use JavaScript" at chrome://settings/content/javascript.

A caveat about verification

Be careful about how you confirm it worked. As that guide points out, "formatted text, images, and a result in the DevTools console do not by themselves confirm that a web page's scripts ran." Reloading an interactive site like Gmail or YouTube is a more reliable real-world test.

One last note: the per-site JavaScript exception is specifically a Chrome feature. Firefox's equivalent documentation is a separate system, and Firefox doesn't offer the same granular per-site JavaScript toggle through the address-bar icon.

The easiest and most reliable way to enable JavaScript for a single website depends on the browser you are using:

Google Chrome / Microsoft Edge / Chromium Browsers

Method 1: Directly from the Address Bar (Quickest)

• 1.Navigate to the website.
• 2.Click the Site Information / Permissions icon in the address bar (it looks like a set of tuning sliders or a padlock, just to the left of the URL).
• 3.Click Site settings (or look directly for JavaScript in the menu).
• 4.Find JavaScript in the list and change the drop-down to Allow.
• 5.Return to the tab and click Reload.

Method 2: From Browser Settings (Whitelist)

• 1.Open Settings:

• Chrome: Go to chrome://settings/content/javascript in your address bar.
• Edge: Go to edge://settings/content/javascript.

• 1.Scroll to the Allowed to use JavaScript section.
• 2.Click Add and enter the website URL (e.g., `example.com` or `[*.]example.com` to include all subdomains).

Apple Safari (macOS)

• 1.Open Safari and open the website you want to allow.
• 2.In the top menu bar, click Safari > Settings (or Preferences).
• 3.Click the Websites tab at the top.
• 4.In the left sidebar, click JavaScript.
• 5.On the right, find the website under Currently Open Websites and change the toggle/dropdown next to it to Allow (or On).

Brave Browser

If you use Brave and have scripts blocked via Brave Shields:

• 1.Go to the website.
• 2.Click the Brave Lion icon in the address bar to open Shields.
• 3.Click Advanced Controls (if collapsed).
• 4.Turn off Block Scripts (or toggle Shields down for that specific site).

Mozilla Firefox

Firefox does not include a built-in per-site whitelist setting for JavaScript in its standard preferences menu.

• If you blocked scripts globally via about:config:

You cannot whitelist single sites natively this way.

• The best approach for Firefox:

Use an extension such as uBlock Origin or NoScript:

• With uBlock Origin: Click the extension icon on the site, then click the </> (Disable JavaScript) button to toggle it back on for that domain.
• With NoScript: Click the NoScript icon and select Trust or Temp. TRUST for that domain.

Using an Extension (uBlock Origin, NoScript, etc.)?

If JavaScript was turned off by a content blocker or security extension rather than your browser settings:

• 1.Click the extension’s icon in your browser toolbar while on that website.
• 2.Click the button to allow scripts or add the domain to the extension's whitelist.
• 3.Refresh the page.

The best way is usually to open your browser’s site permissions and allow JavaScript for that one domain only, rather than turning it on globally.¹²¹⁰

In Chrome, go to Settings → Privacy and security → Site settings → JavaScript, then either leave JavaScript enabled globally and add the site to the allowed list, or set it to block by default and allow only the specific site you want.¹⁶¹¹ Chrome also lets you change permissions from the site itself by opening the site info panel next to the address bar and choosing Site settings.¹

If you want the exact pattern for a single site, examples like *[.]example.com are supported in browser policy settings and in browser help pages that show adding site-specific allow rules.⁴⁸ In Microsoft Edge, the equivalent policy-based setting is JavaScriptAllowedForUrls**, which allows JavaScript on specific URL patterns.¹⁴

If you tell me which browser you use—Chrome, Edge, Safari, Firefox, or another one—I can give the exact clicks for that browser.

The best way is to allow JavaScript only for that site in your browser’s site settings (or in a blocker extension). JavaScript is on by default in modern browsers, so if one site needs it, something is usually blocking it specifically.

Chrome, Edge, and other Chromium browsers

Fastest (for the site you’re on):

• 1.Click the icon to the left of the address bar (lock, tune/sliders, or info icon).
• 2.Open Site settings.
• 3.Set JavaScript to Allow.
• 4.Reload the page.

Or manage exceptions:

• 1.Go to chrome://settings/content/javascript (Edge: edge://settings/content/javascript).
• 2.Either:

• Keep Sites can use JavaScript and remove the site from Not allowed, or
• Set the default to Don’t allow sites to use JavaScript, then under Allowed to use JavaScript click Add and enter the site (for example `example.com` or `[*.]example.com` for all subdomains).

Firefox

Firefox does not have a simple built-in allow-list for JavaScript. Options:

• Check the shield icon in the address bar and turn off enhanced tracking protection for that site if it’s interfering.
• If you use an extension such as NoScript, uBlock Origin, or similar, allow scripts for that site in the extension’s popup.
• Global on/off is under about:config → javascript.enabled (set to true). That is all-or-nothing, not per site.

Safari (Mac)

• 1.Safari menu → Settings → Security.
• 2.Check Enable JavaScript.

Per-site control is limited. For finer control, use an extension, or check Settings → Websites for related content settings.

Also check these

• Extensions: Content blockers (uBlock Origin, NoScript, AdGuard, Privacy Badger, etc.) often block scripts. Open the extension’s icon on that site and allow JavaScript / scripts, then reload.
• Managed browser: On a work or school device, policy may force JavaScript off. Check chrome://policy or edge://policy for JavaScript-related policies; you may need an admin to change it.
• After changing the setting, do a normal reload (or hard reload) so the new permission applies.

If you say which browser and device you’re using (and whether an extension is involved), the steps can be narrowed to that exact case.

I'll look up the per-site JavaScript controls for Chrome, Edge, Firefox, and Safari.

I've found the key differences by browser — now I'll open the official guides to verify the exact steps.

The best way is not to change your global setting — add a per-site exception for just that site.

That way you can keep JavaScript blocked everywhere else for privacy/security, but let a trusted site run.

Chrome on desktop - best method

Chrome lets a site "use its settings instead of the default settings."

• 1.Open Chrome and go to that site.
• 2.To the left of the web address, select View site information.
• 3.Select Site settings.
• 4.Change the JavaScript permission to Allow.

Your changes save automatically — just reload the tab.

This is best because sites usually use JavaScript to display interactive features, like video games or web forms, so you only fix the one site that is broken.

Alternative - from Settings:

Go to chrome://settings/content/javascript — you'll see a “Block” and “Allow” section. Select “Add” next to Block or Allow, depending on if you want to disable or enable JavaScript on a site.

Add the site URL under Allowed to use JavaScript.

Microsoft Edge on desktop - best method

JavaScript is on by default; you only need this if it was turned off. Edge, like Chrome, lets you add a per-site exception without changing the global setting.

Option A - From the address bar - fastest:

1. Open the affected site in Edge. 2. Click the tune icon or lock icon on the left side of the address bar. 3. Click Permissions for this site. 4. Find JavaScript and change it from Block to Allow. 5. Reload the page. JavaScript will now run on that site only.

Option B - From Settings:

Paste edge://settings/content/javascript into the address bar. The Allowed to use JavaScript and Not allowed to use JavaScript lists each have an Add button - paste the site URL there.

Firefox

Firefox doesn’t offer a built-in feature to enable JavaScript for specific sites, but you can use browser extensions to manage this.

While there isn’t a native UI option for enabling JavaScript for specific sites when it’s globally disabled, users can rely on add-ons or extensions that provide website-specific control

Best practice in Firefox:

• 1.Leave JavaScript enabled globally — about:config > javascript.enabled = true.
• 2.If you want per-site blocking, install an extension like NoScript and select “Trusted” or “Untrusted” for specific websites.

You can't disable JavaScript only for specific sites in Firefox as you can do in Chrome.

Safari on Mac / iPhone

Safari does not allow enabling JavaScript on a per-site basis. You must enable it globally

No, iOS does not currently allow enabling JavaScript on a per-website basis... JavaScript can only be enabled or disabled globally

To turn it on globally:

On Mac, choose Safari > Settings > Security and select Enable JavaScript. On iPhone or iPad, open Settings > Apps > Safari > Advanced and turn on JavaScript.

Bottom line: If you use Chrome or Edge, use the lock/tune icon > Site settings / Permissions for this site > JavaScript > Allow. That's the safest way to turn on JavaScript for a specific website.
