HTTP Strict Transport Security on Merlin, OpenDNS blockpage not showing in certain browsers

[TheBlindKind]

Hi, I've been looking around the Merlin software on my new router for a way to add exceptions to certificate errors for HTTP Strict Transport Security so that the Open DNS block page will come up when navigation to a blocked site is attempted. I get the HTTP Strict Transport Security error about mismatched pinning, etc., where I didn't get that on the old router. I would really like to be able to see that block page again for blocked domains under browsers other than internet explorer. Where on the Merlin web UI can I make this happen, if possible? I'm completely new to this. Any help would be greatly appreciated.
