This is mostly for TEST Tnew instances so that cookies can work between the SS & Test TNEW instances (Firefox is more locked down)

  1. Go to Preferences/Settings
  2. Go to "Privacy & Settings"
  3. Scroll down to "Cookies and Site Data"
  4. Click the "Manage Exceptions" button
  5. Add the SS domain and click "Allow" (this will mimic Google Chrome on devspace)
  6. Add the TNEW (.cloud) domain and click "Allow" (this will mean the devspace workaround will not be needed and it will 100% work like live)
  7. Click "Save Changes"
