How to get rid of a message - "can't verify the identity of the website"

[forprocessing]

I keep getting these messages (please see the attachment). I can hit "Cancel", and the website loads fine, but it is annoying and disruptive having to do it a lot. Is there any way to get rid of this message? I suspect it may have something to do with PFBlockerNG, but not sure and do not know how to proceed…

Thank you.

See the checkbox? Tick it and click Continue.

But then I have to do it for each and every time it pops up, and it keeps popping up a lot. Is there a way to address this at a firewall level? So I stop getting these error messages?

Well, your other option are

• use a browser than doesn't produce retarded pop-ups
• stop using DNSBL

We have a winner here! (I hope :-))

Added a firewall rule and so far so good. If this works - this is indeed the answer I was looking for.
