How to Find a Cookie ID (Value) in Chrome, Firefox, Safari, Edge & More

Finding a specific cookie’s ID or value in your browser can help with troubleshooting or ensuring your website’s cookies are set correctly. Modern browsers provide built-in developer tools to view and filter cookies by name. Below are step-by-step guides for Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge.

Google Chrome
  1. Press F12 (Win) or ⌥+⌘+I (Mac) to open DevTools.
  2. Open Application.
  3. In the left panel, go to Storage > Cookies.
  4. Select your site’s domain.
  5. Use the Filter box to search by cookie name.
  6. Read the Value column (that’s the cookie ID/content).

Tip: turn on Show URL decoded if the value looks encoded

Other Chromium-based browsers (Brave, Comet, Vivaldi, Opera)

These browsers use Chromium DevTools, so the steps match Chrome:

  1. Open DevTools (F12 or Ctrl+Shift+I / ⌥+⌘+I).
  2. Go to Application > Storage > Cookies.
  3. Select your site’s domain, use Filter to find the cookie, read the Value.

Tip: turn on Show URL decoded if the value looks encoded

Note about ChatGPT Atlas (macOS app): If View > Toggle Developer Tools is available, you can follow the same Application > Storage > Cookies steps inside the app. If DevTools isn’t exposed, sign in via a browser and use that browser’s steps.
