Reproducible: Always Steps to Reproduce: 1. Go to Tools - Advanced Tab - View Certificates. 2. Under Certificate Manager, try to delete ABA ECOM Root CA certificate. 3. Restart Firefox. (Closing and restarting Certificate Manager without full restart happens as well) 4. "Deleted" certificate is back. Actual Results: There is no real deletion.
