My Firefox was updated last night to v111.0 and, when I logged on this morning, a site that I have used daily for several months did not connect bacause of a potential security issue. The site is one of the Cher French Archives (www.archives18.fr) and the error code is MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT. Per your instructions, I should be able to "Accept the Risk and Continue" on the ADVANCED page. However, that option is not available when I jump to the ADVANCED page. Please help! This is a valid site.
