Using an invalid security certificate

I tried with Opera 46 (Chrome 59)
Firefox 52.2.0 (ESR 32bit)
Firefox 54.0 (Stable 64bit)

All worked fine.
What I suspect though is that Firefox uses the wrong certificate.
Our certificate for Techspot is only valid for techspot.com and www.techspot.com.
You should be seeing a certificate from stacksocial.com when you are on store.techspot.com.
If you get the error again try to confirm this, a printscreen might help.
That said it sounds like a browser cache issue to me.
 
Don't think certs are cached due to expiration date issues - - BUT - - if I see it again I'll try to be more precise.
 
I tried this a couple of days back... unrelated to HTTPS since it's the store. No issues on different browsers.
 
Ahh right, this was before our switch to https for Techspot's main site.
Then I'm sure it must have been some error with the cert itself.
Firefox is, unlike other browsers actually following the RFC standards.
And this can sometimes hurt it.
See for example: "Firefox is considering giving up on OCSP for DV certs"
https://bugzilla.mozilla.org/show_bug.cgi?id=1366100
It was mentioned in Security Now! episode #613

There are other such cases, for example very recently several Microsoft sites went down.
Because of a OCSP error in their certificate.
Of course it only affected Firefox because they are the only ones to implement it fully!

YEAH! Standards are a two-edged sword; Until the 'Majority' become compliant, there's always pain :grin: (y)
