Are Google and Firefox having a fight?

I can sign onto gmail from Chrome or IE no problem, but Firefox tells me that gmail is an untrusted connection. What gives?
This has been going on for a couple of weeks. Prior to that, I happily only had one browser open during the day. What am I doing wrong?
This remains true even though firefox was just reloaded to my computer by an IT professional.

Are you on a corporate network? If so, chances are it's due to the company proxy doing a man in the middle attack so they can monitor your internet usage. Bitdefender can also mess it up if you have ssl scanning enabled.

Response by poster: do you get the same error everywhere? have you tried both at work and at home (without vpn)?
Have not tried at home b/c I don't use firefox at home. But this really only started a week or two ago.
what does the error say in more detail?
gmail.com uses an invalid security certificate.
The certificate is not trusted because the issuer certificate is unknown.
The server might not be sending the appropriate intermediate certificates.
An additional root certificate may need to be imported.
(Error code: sec_error_unknown_issuer)
what is your os?
Microsoft Office Professional Plus 2010
what version of firefox are you using (menu, "?", about)?
42.0

a better way to see the actual Certificate Authority is to do a search like this:

This is exactly what I deal with work, something I've carefully confirmed. Firefox is the only major browser that picks it up and warns you -- Chrome, IE, etc just happily plug away as if all is well.
Your company is snooping on your ostensibly end-to-end encrypted web traffic-- it's just that FF is the only browser telling you that it's happening.
