I get the same kind of fascination reading those comment threads as one would get watching a train wreck. To multiple users telling them that their stuff is broken, they reply that this is their actual intent. The thought that maybe there might be a flaw in their design does not cross their minds an instant. "Am I out of touch? No, it is the users who are wrong."

I particularly love the suggestion to use https://ideas.mozilla.org/ to submit feedback, as if that change went through the same procedure, and as if they didn't moderate away any suggestion that they don't like.

And yet they still don't realize that this "we know better than the users what's good for them" attitude is killing their product.
