ok, bit wierd but its sorted itself out after a reboot?!?!
so now even when i dont whitelist the websites, when i go on them, instead of getting the cert error message, i get now the normal error message, saying access denied by your admin

What prevents you from viewing the certificate? Can you click on the
site information icon to the left of the browser Location(?) bar when
the error is displayed? If not, perhaps you can use FireFox built-in
"Web Developer Tools" (Ctrl-Shift-I on my machine) to get to the
certificate? I am not a browser expert, but there is usually a way to
see the certificate if the browser received it.
If nothing works, can you try reproducing using curl or wget instead of
a browser?

That would give you the third certificate to compare.
