Extension not loading in Tableau Server or Tableau Online

Cause: Some extensions (like WriteBackExtreme) require access to 3rd-party cookies to function properly, especially when running inside Tableau Online or in embedded dashboards.

Symptoms:

• The extension fails to load or appears blank

• No interaction or data appears in the extension window

Resolution: Make sure 3rd-party cookies are enabled in your browser.

How to enable:

• Follow the instructions in our step-by-step GIF:

• You can also check your browser’s settings under:

  • Chrome: Settings → Privacy and Security → Cookies

  • Edge: Settings → Site Permissions → Cookies and site data

  • Firefox: Settings → Privacy & Security → Enhanced Tracking Protection

🔐 Enabling 3rd-party cookies does not compromise your data security. Extensions run securely inside Tableau and follow GDPR-compliant practices.
