Security software

To use SSL protocol, Firefox needs to make a connection to itself. Some security software can block this connection. For information on how to configure security software to allow Firefox the access it needs, see Firewalls.
Problem with a specific siteYou can test your browser for SSL functionality. If your browser passes the test, the problem may be specific to the site you're trying to access.
