Certificate error on some Google domains
Hi,
I am getting an SEC_ERROR_UNKNOWN_ISSUER on some (but not all) Google domains, YouTube for example. I am only getting the certificate error inside Firefox (I also have Chrome and Safari and they don't report a problem) and I *am* continuing to get the error while in safe mode (with all extensions disabled). I have added the troubleshooting info to this post, so feel free to check out the plug-ins I have installed.
I have read the troubleshooting guide on SEC_ERROR_UNKNOWN_ISSUER and I do not have any of the problems listed there. For example: I do not have any AV installed and my timezone and date/time are correct.
I've gone though the certificate chain (see reply - the chain is too large to put into this post) and the root cert looks off to me. It claims to be 'GeoTrust Global CA' but the fingerprint does _not_ match the fingerprint of the cert visible in the Certificate Manager (Preferences -> Privacy & Security -> View Certificates -> Authorities -> GeoTrust Global CA -> View) and the Issuer is 'O=Equifax, OU=Equifax Secure Certificate Authority' whereas it should be 'O=GeoTrust Inc. OU=GeoTrust Global CA'.
I think this problem only manifested itself yesterday (perhaps the day before), and I haven't installed any new software recently (although it is possible something may have updated itself).
Now, I suspect that I could make this all go away by trashing or refreshing my profile, but I'd quite like to know where this cert is coming from. If I do happen to have a rouge plugin (or similar) then I'd prefer to know.
All help and suggestions welcome. Thanks in advance!

I have just seen the discussion at https://support.mozilla.org/en-US/questions/1200716 and I see that this seems to be a (hopefully temporary) problem with the Google OCSP server.
I'll set 'security.OCSP.require' to 'false' for the next couple of days. Hopefully Google will fix this soon.

I have just seen the discussion at https://support.mozilla.org/en-US/questions/1200716 and I see that this seems to be a (hopefully temporary) problem with the Google OCSP server.
I'll set 'security.OCSP.require' to 'false' for the next couple of days. Hopefully Google will fix this soon.
