I do not, did not, and never have faulted the original Netscape engineers. They did the best job that they could at the time. In particular, Netscape predates SSH, and SSH was the first program to demonstrate that crypto is much easier to deploy without a PKI. (SSH is also, incidentally, the only crypto protocol in history successful enough to have driven its corresponding unencrypted alternative to extinction.) I also fully agree that cryptographers are largely at fault for the colossal PKI mistake.

But Firefox was developed well after the rise of SSH, and the particular design decision that I am criticizing, namely the decision to change the warning dialogs for unauthenticated encrypted connections from one mild warning to three consecutive very big scary warnings, was made in Firefox 2.0, released in 2006. The Netscape engineers had valid excuses for their mistakes. The Firefox engineers do not.
