How to Enable JavaScript on Vivaldi
Vivaldi is a Chromium-based browser built by ex-Opera engineers and aimed at power users. JavaScript is enabled by default on every Vivaldi platform - Windows, macOS, Linux, Android, and iOS. If a site is blank or showing a "Please enable JavaScript" message in Vivaldi, the toggle has been switched off somewhere in your settings, often by a workspace import from Chrome or by Vivaldi's built-in tracker blocker hitting a script it considered hostile.
This guide covers every Vivaldi scenario: enabling JavaScript globally on desktop, allowing it for a single site, the vivaldi://settings shortcut, the Android flow, and the iOS flow (which goes through iOS Settings rather than Vivaldi). All steps reflect Vivaldi 7.x in 2026.
Enable JavaScript globally in Vivaldi on Windows 11
Step 1: Open Vivaldi
Launch Vivaldi from the Start menu or taskbar.
Step 2: Open Settings
Press Ctrl + F12 on Windows. Or click the Vivaldi menu (V icon top-left) and choose Settings.
Step 3: Open Webpages
In the left sidebar of the Settings window, click Webpages.
Step 4: Find the JavaScript section
Scroll to the Webpage Permissions section. Click Manage Webpage Permissions. Vivaldi opens its underlying Chromium permissions page.
Step 5: Open the JavaScript permission
Click JavaScript in the Content list.
Step 6: Set "Sites can use JavaScript"
Under Default behavior, select Sites can use JavaScript. The change is instant. Reload any open tab.
Enable JavaScript globally in Vivaldi on macOS Sequoia
Step 1: Open Vivaldi
Launch Vivaldi from Launchpad, Spotlight, or the Dock.
Step 2: Open Settings
Press Cmd + ,. Or click Vivaldi → Settings in the macOS menu bar.
Step 3: Open Webpages
Click Webpages in the left sidebar.
Step 4: Manage Webpage Permissions
Scroll to Webpage Permissions and click Manage Webpage Permissions.
Step 5: Open the JavaScript permission
Click JavaScript.
Step 6: Set "Sites can use JavaScript"
Select Sites can use JavaScript. The change applies immediately, no Save button required.
The fast path: vivaldi://settings/content/javascript
Skip the menu entirely. Type or paste:
vivaldi://settings/content/javascript
Press Enter and Vivaldi takes you straight to the JavaScript permission page. Same toggle, same allow-list, no clicking through Webpages and Manage Webpage Permissions. Bookmark it if you flip the switch often.
Other useful Vivaldi shortcuts:
vivaldi://settings/content- the full Site settings page (all permissions).vivaldi://settings/privacy- the broader Privacy and security panel.vivaldi://settings- Vivaldi's own settings UI (Webpages, Tabs, Quick Commands, etc.).
Vivaldi's built-in tracker blocker (the second layer)
Vivaldi ships with a built-in ad and tracker blocker that, on its strictest setting, can block JavaScript on individual sites. If JavaScript is on globally but one site is broken in Vivaldi, check the shield icon in the address bar:
- Click the shield icon in the address bar of the affected page.
- Look at the current Privacy Level. If it is Block Ads and Trackers, lower it to Block Trackers Only or No Blocking for this site.
- Reload the page. If it works now, the tracker blocker was misidentifying the site's scripts.
Enable JavaScript on Vivaldi for Android
Step 1: Open Vivaldi on your phone
Tap the Vivaldi V icon to launch the app.
Step 2: Open the menu
Tap the Vivaldi menu (V icon, usually top-right or bottom depending on your toolbar layout).
Step 3: Tap Settings
Choose Settings from the menu.
Step 4: Open Privacy and Security
Scroll to Privacy and Security.
Step 5: Site Settings → JavaScript
Tap Site Settings, then JavaScript.
Step 6: Switch JavaScript on
Toggle JavaScript on. Reload any open tab.
Enable JavaScript on Vivaldi for iPhone and iPad
On iOS and iPadOS, Apple requires every browser to use the system WebKit engine. That means there is no JavaScript toggle inside the Vivaldi iOS app. The setting that controls JavaScript for Vivaldi on iOS lives in the system Settings app and applies to every browser at once.
Step 1: Open the iOS Settings app
Tap the gray gear icon on your home screen or App Library.
Step 2: Tap Apps
Scroll down and tap Apps.
Step 3: Tap Safari
Inside Apps, tap Safari. This controls the WebKit engine that Vivaldi iOS uses.
Step 4: Open Advanced
Scroll to the bottom of Safari's settings and tap Advanced.
Step 5: Enable JavaScript
Toggle JavaScript on (green). The change applies immediately to Vivaldi, Safari, Chrome, Brave, and every other browser on the device.
How to verify JavaScript is now on in Vivaldi
The clearest test:
- Open a new tab and visit any JavaScript-detection page.
- If the page reports JavaScript is enabled, you are done.
- If a single site still fails, click the shield icon for that site and lower Privacy Level.
You can also confirm via DevTools:
- Press Cmd + Option + I (Mac) or Ctrl + Shift + I (Windows, Linux).
- Click the Console tab.
- Type
1+1and press Enter. If the console returns2, JavaScript is running.
