However, I haven’t found any information about whether or not they actually pulled the trigger on their plans. Moreover, in my own efforts I haven’t been able to conclusively decide if public key pinning support has been removed from recent versions of Chrome. This page seems to suggest it was removed in Chrome 72, but I’m not familiar enough with the Chrome development process to be certain that is what it actually says.
So do recent versions of Chrome ignore public key pinning headers? Have Firefox or Opera followed suit?
