Browser-specific Guide

Your browser's security features (known as CORS) will block the API request. The instructions below explain how to bypass this by using browser-specific extensions or altering settings.

Chrome icon Google Chrome

For Chrome, the easiest method is to use a browser extension that disables CORS checks.

  1. Install CORS Unblock: Install the CORS Unblock extension (or a similar alternative).
  2. Pin the Extension: Click the puzzle piece icon (Extensions) in your toolbar. Find "CORS Unblock" in the list and click the pin icon next to it. This will keep the extension's icon visible in your toolbar for easy access.
  3. Enable the Extension: Click the newly pinned icon for the "CORS Unblock" extension to activate it. The icon will usually change color to indicate it is active.

Firefox icon Mozilla Firefox

Similar to Chrome, you can use an add-on to manage CORS headers in Firefox.

  1. Install CORS Everywhere: Install the CORS Everywhere add-on.
  2. Pin the Extension: Right-click the "CORS Everywhere" icon in your toolbar and select Pin to Toolbar if it is not already visible.
  3. Activate the Add-on: After installation, click the icon in your toolbar to toggle the add-on on or off. The icon will turn green to indicate it is active.

Safari icon Apple Safari

Safari has a built-in feature for developers that can disable CORS restrictions without needing an extension.

  1. Enable the Develop Menu: Open Safari, go to Safari > Settings (or Preferences) from the menu bar. Click on the Advanced tab and check the box at the bottom that says "Show Develop menu in menu bar."
  2. Disable Cross-Origin Restrictions: You will now see a new "Develop" menu in the menu bar. Click on it, and then check the option Disable Cross-Origin Restrictions.
  3. Keep in Mind: This setting will reset every time you close Safari, so you will need to re-enable it for each new session.

Important Security Warning

These methods disable important security features in your browser. They are safe for using the our dataset tools, but you should always disable these extensions or revert the settings before browsing the web normally.
