Good Day, I'm using Firefox 107.0 . I have two expired personal certificates issued by SAP, a very large Business Application Company. I also have a current recently issued certificate that doesn't expire until Nov. 2023. Trying to connect to the Support site for the Company, I'm informed that my certificate has expired. I expect that's because the certificates are listed in order of oldest to newest, and the expired certificates are hit before the new one, which is likely not checked. I go into Privacy and Security Settings, to the View Certificates option, and delete the two expired certificates, then click OK. I go back to view the certificates, and the deleted certificates are still there. I still cannot connect to the Company site. When is was using MS IE, i was able to delete expired certificates without any issue. How can i safely delete expired Personal Certificates in Firefox, without having to delete many other things that I do not want to have to deal with re-establishing, which would be a significant time sink. Thank you! George P.
