I'm sure you're right. It was on whatever version of Firefox was on my work laptop the week I learned Golang, since my first project with the language was an HTTPS/SSL proxy. I even griped about it on Twitter (it breaks Golang's crypto/tls), and (after we'd hacked support for it into our local tree) got a link to a patch. That would have been... meh... a year and a half two years ago.
