JavaScript inschakelen in Opera

Opera is sinds 2013 gebouwd op Chromium, dus de JavaScript-instellingen lijken sterk op die van Chrome en Edge. Hetzelfde geldt voor Opera GX, de variant voor gamers. JavaScript staat standaard aan; deze gids hebt u alleen nodig als JavaScript was uitgezet.

Deze gids toont de globale JavaScript-schakelaar, de opera://settings-snelkoppeling en hoe u JavaScript voor één specifieke site toestaat.

JavaScript inschakelen in de Opera-browser

Opera is een op Chromium gebaseerde browser, dus de JavaScript-instellingen lijken op die van Chrome. Stappen:

  1. Open Opera en klik rechtsboven in het venster op Eenvoudige instellingen (of het menu met drie streepjes).
  2. Scroll naar beneden en kies Ga naar browserinstellingen (of typ opera://settings rechtstreeks).
  3. Kies in de zijbalk Privacy en beveiliging.
  4. Ga naar Site-instellingen → JavaScript.
  5. Kies Sites mogen JavaScript gebruiken.

U kunt in Opera ook rechtstreeks naar opera://settings/content/javascript gaan via de adresbalk.

Opera heeft JavaScript standaard aanstaan, dus deze stappen zijn alleen nodig als JavaScript was uitgeschakeld of als u per site wilt instellen. In Opera GX (de variant voor gamers) zijn de stappen identiek.

How to Enable JavaScript in Opera on Windows 10 and Windows 11

The Opera JavaScript toggle is in the same place on Windows 10 and Windows 11 - the browser ships an identical Settings UI on both. Opera 105 and later (the modern Chromium-based release) follows these six steps:

Step 1: Open Opera

Launch Opera from your Start menu or taskbar.

Opera browser open on a Windows 11 desktop
Opera running on Windows 11.

Step 2: Open the Easy Setup menu

Click the red Opera "O" menu in the top-left corner, or open the Easy Setup panel in the top-right. Either entry point reaches the Settings page.

Open Settings via the Opera menu or the Easy Setup panel.

Step 3: Open Site settings

Inside Settings, click Privacy & security in the left sidebar (you may need to expand Advanced first), then choose Site Settings.

Opera Site Settings panel open on Windows 11
Site Settings is where every per-content permission lives.

Step 4: Open the JavaScript permission

Scroll to the Content section and click JavaScript. The shortcut opera://settings/content/javascript jumps straight here.

Step 5: Select Sites can use JavaScript

Under Default behavior, choose Sites can use JavaScript. Opera saves the change instantly.

JavaScript default behavior set to Sites can use JavaScript on Windows 11 Opera
JavaScript is now allowed on every site by default.

Step 6: Verify (optional) - and how to turn it off

To confirm, reload any interactive site (YouTube, Gmail, Facebook). If you ever need the opposite, pick Don't allow sites to use JavaScript on the same screen:

JavaScript default behavior set to Don't allow sites to use JavaScript on Windows 11 Opera
The same toggle in the disabled state.

JavaScript is now enabled across every site you visit. The same flow works for Opera GX - the gaming-themed sibling shares the same Chromium settings UI. Add specific sites to the Not allowed list on the same page if you want to block scripts only on certain pages.

How to Enable JavaScript in Opera on Mac (macOS Sonoma, Sequoia, and macOS 26)

The macOS version of Opera - on macOS Sonoma, Sequoia, and macOS 26 - uses the same Chromium-based Settings UI as the Windows build. Follow these five steps:

Step 1: Open Opera

Launch Opera from your Dock, Launchpad, or Applications folder.

Opera browser open on macOS 26
Opera running on macOS 26.

Step 2: Open Settings, then Site Settings

From the macOS menu bar choose Opera → Settings... (or press Cmd+,). In the Settings page sidebar, click Privacy & security, then choose Site Settings.

Opera Settings page open on macOS 26 with Site Settings highlighted
Site Settings is where every per-content permission lives in Opera for Mac.

Step 3: Open the JavaScript permission

Scroll to the Content section and click JavaScript. The shortcut opera://settings/content/javascript jumps straight here.

Opera JavaScript permission page open in Site settings on macOS 26
The JavaScript permission page inside Opera Site settings on macOS.

Step 4: Select Sites can use JavaScript

Under Default behavior, choose Sites can use JavaScript. The change saves immediately.

JavaScript default behavior set to Sites can use JavaScript on macOS 26 Opera
JavaScript is now enabled by default for every site.

Step 5: How to turn it back off

To disable JavaScript later, return to the same screen and pick Don't allow sites to use JavaScript:

JavaScript default behavior set to Don't allow sites to use JavaScript on macOS 26 Opera
The same toggle in the disabled state.

That's it. Reload any interactive site (YouTube, Gmail, Google Docs) to confirm scripts now run as expected. The same flow works for Opera GX on macOS - the gaming-themed sibling shares the same Chromium settings UI.

How to Enable JavaScript in Opera on iPhone, iPad, and iOS

On iPhone and iPad, every browser - including Opera, Opera GX, Chrome, Edge, Firefox, Brave, and DuckDuckGo - is required by Apple to use the system WebKit engine. That means there is no JavaScript toggle inside the Opera iOS app itself. The setting that controls JavaScript for Opera on iOS lives in the system Settings → Apps → Safari → Advanced screen, and it applies to every browser at once.

Step 1: Open the Settings app

Tap the gray gear icon on your home screen or App Library to launch iOS Settings.

iOS Settings app icon on the iPhone home screen
Open the Settings app on your iPhone or iPad.

Step 2: Open Apps

Scroll down and tap Apps. (On iOS 17 and earlier, Safari appears directly in the main Settings list - tap it instead.)

The Apps section consolidates per-app system settings.

Step 3: Select Safari

Inside Apps, scroll to and tap Safari. This is where iOS controls the WebKit engine that Opera iOS uses behind the scenes.

Safari is the gateway to JavaScript settings for every iOS browser.

Step 4: Tap Advanced

Scroll to the bottom of the Safari settings page and tap Advanced.

The Advanced page contains the JavaScript switch.

Step 5: Enable JavaScript

Toggle the JavaScript switch on (green). The change applies immediately to Opera, Safari, and every other iOS browser.

JavaScript enabled for every browser on iOS.

Step 6: How to turn it off again

To disable JavaScript later, flip the same switch off (gray). Note that almost every modern site will break without it.

The same toggle in the disabled state.

Now switch back to Opera iOS and reload your tab - JavaScript is on (or off) for every browser on the device.

JavaScript per site toestaan of blokkeren in Opera

Wilt u JavaScript niet globaal aan/uitzetten maar per site:

  1. Open de gewenste site.
  2. Klik op het slot-icoon links in de adresbalk.
  3. Kies Site-instellingen.
  4. Zoek JavaScript en kies Toestaan of Blokkeren.
  5. Vernieuw de pagina om de wijziging toe te passen.

Of u beheert direct vanuit opera://settings/content/javascript de lijsten "Toegestaan" en "Geblokkeerd".

Veelgestelde vragen

Hoe controleer ik of JavaScript werkt in Opera?

In Opera staat JavaScript standaard aan, maar u kunt het verifiëren. Klik in Opera rechtsboven op "Eenvoudige instellingen". Scroll naar beneden en kies "Ga naar browserinstellingen". Typ in het zoekveld "JavaScript" - de instelling moet op "Sites mogen JavaScript gebruiken" staan.

Wat gebeurt er als ik JavaScript uitschakel in Opera?

Veel sites gebruiken JavaScript om dynamische content (animaties, speciale effecten) te tonen. Met JavaScript uit in Opera krijgt u niet de volledige ervaring: sommige sites zien er kaal uit, andere missen functies.
