Dude, the existence of the extension was the promotion. And Mozilla was paid for it. And the bug report is still hidden showing they have not learned their lesson. Why are you defending bad behavior?
People weren't supposed to be finding it like that. I really don't think "oh what is this new firefox experiment?" was an intended promotional path. It was an extension because that was easier to do and isolate. That's why I'm defending the intent.
And I don't think the visibility of a bug report tells us whether they learned their lesson.
