Do I Need JavaScript Enabled to Use Tab Butler?

Updated

Yes. Tab Butler (tabbutler.netlify.app) is a JavaScript-rendered web app, and its own page states: "You need to enable JavaScript to run this app." With JavaScript disabled or blocked, the page will not load the tab manager interface, so you cannot use the tool until JavaScript is enabled for that site.

What the page tells you

The only content the site serves without running scripts is the JavaScript notice. That means the interface, controls, and any tab-management features are built by scripts in the browser. If scripts are blocked, there is nothing to interact with.

Situation What you see Can you use Tab Butler?
JavaScript enabled The app interface loads Yes
JavaScript disabled "You need to enable JavaScript to run this app." No
Scripts blocked by an extension or policy Same notice, or a blank page No, until the block is lifted

How to check and enable JavaScript

Chrome or Edge (desktop)

  1. Open chrome://settings/content/javascript (Edge: edge://settings/content/javascript).
  2. Confirm that sites are allowed to use JavaScript, and that tabbutler.netlify.app is not in the "Not allowed" list.
  3. Reload the page. Expected result: the Tab Butler interface appears instead of the notice.

Firefox (desktop)

  1. Open about:config and check that javascript.enabled is true, or use Settings → Privacy & Security → Permissions and confirm JavaScript is enabled.
  2. If you use an extension such as NoScript, allow tabbutler.netlify.app.
  3. Reload the page.

Safari (macOS)

  1. Safari → Settings → Security → enable "Enable JavaScript."
  2. Reload the page.

Mobile browsers

Most mobile browsers enable JavaScript by default. If the notice still appears, check the browser's site settings for tabbutler.netlify.app and make sure script blocking or "reader"-style modes are off.

Common reasons it still fails

  • Content blockers or privacy extensions blocking scripts on netlify.app domains. Disable the blocker for this site and reload.
  • Corporate or school network policies that strip scripts. Try another network or device to confirm.
  • Strict browser modes (for example, hardened privacy configurations) that disable JavaScript globally. Allow it for this site only.
  • A stale cached page. Do a hard reload (Ctrl+Shift+R or Cmd+Shift+R) after changing settings.

If the interface loads after these steps, JavaScript was the blocker. If the notice persists with JavaScript confirmed on and blockers off, the issue is likely network-level filtering rather than your browser settings.
