Suggestion: Show HSTS and HPKP status

HSTS = HTTPS Strict Transport Security
HPKP = HTTPS Public Key Pinning

+1 It is not very intuitive to get these information out of the debugger by now. An information which pin is used for the connection (on multi pin headers) would be useful too.

By the looks of it, that extension is parsing SiteSecurityServiceState.txt (in your Fx profile directory). I wonder if there isn't an existing API that could be used instead.
