How to remove "security exception" for a certificate-expired site
When I bring up the certificate-expired URL
<https://oaklandwiki.org/>
in Firefox 149.0 on Windows 11 I am told "You have added a security exception for this site." But not how to remove it. How do I do that? I did not see anything in Settings or about:config; did I miss it?

Go to Tools -> Settings -> Privacy & Security. Scroll down to the Certificates section and click the Manage certificates button. Click the Servers Tab/Section. The one you want to remove should be in this list. Highlight it and a Remove button should appear.
Yes, it looks like that did it; I get the warning message back. Thanks!

Thanks! There is a newer version of that wiki page, so I was able to simply rename the problematic links, but your cites are good to know about.
