In the last 2-3 days I have been getting "This Connection is Untrusted" screens when trying to navigate to a number of https sites, including Google+, Vanguard, and others. I try to confirm the security certificates and add exceptions, but even after I do that, the sites do not load properly (for instance, no pictures or images).
The problem is not occurring when I use IE on the same computers to navigate to the same sites.
Any ideas as to what's going on and how to fix it?
You're not going to fix it. If anything Firefox is the one behaving correctly.
The backstory on this:
Someone--presumed to be Iran but this isn't proven--hacked the Dutch certificate authority
www.diginotar.com and issued themselves a bunch of bogus certificates. This is a pretty severe breach in the first place and DigiNotar hasn't exactly been doing a good job of dealing with it, either.
The digital certificates are all about trust and DigiNotar has shown that it's not trustworthy.
Mozilla responded by removing the DigiNotar root certificate from the latest update. This will cause certificate errors for any site that used a DigiNotar-signed certificate. Since this is a deliberate decision and not a bug don't expect it to change unless the situation changes.
I believe Chrome has done the same thing.
