When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.
Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):
- github.io (many subdomains)
- purdue.edu (many subdomains)
- iu.edu
- ebay.com
- cbsnews.com
- iwm.org.uk
- home.cern
- celestrak.org
Any help in resolving this is appreciated.
