firefox suddenly stopped allowing access to Https sites, saying the sites are untrusted. Chrome and ie allow them. What's up?
Windows 7 64 bit
The sites in question are all sites that I've used frequently, they are trusted. When I read the details on the warning page at least one site had a valid certificate based on the dates. The reasons given are not all "expired" there are several others. Here's another example:
www.bankofamerica.com uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
