I have client who keeps getting security warnings from their office using FF 3.6. I cannot reproduce using same exact browser at my location. Client says they are getting complaints from some people about the error as well.
I know someone who gets the error in Safari, but I do not. I know someone else, who, like me, does not get security warnings on any browser or computer.
I went to another location which used FF and indeed, I saw the error.
What could possibly be causing this. I'm running Debian Linux.
