python
import requests

def check_certificate_status(url):
try:
response = requests.get(url)
if response.status_code == 200:
print("Certificate is valid.")
else:
print("Certificate is invalid.")
except requests.exceptions.RequestException as e:
print("An error occurred while checking the certificate status:", e)

# Example usage
ocsp_url = "https://ocsp.example.com"
check_certificate_status(ocsp_url)

In this sample code, the `check_certificate_status` function takes an OCSP URL as input and makes a GET request to that URL. If the response has a status code of 200, it prints that the certificate is valid; otherwise, it prints that the certificate is invalid. The code includes basic error handling for any exceptions that may occur during the request.

Please note that this code is a general example and may not directly address the specific issue you mentioned. It is crucial to refer to official documentation or consult with experts to implement a precise fix for SEC_ERROR_OCSP_FUTURE_RESPONSE in Firefox.
