The biggest problem, for me, is that these extensions obviously get less scrutiny in Mozilla organization. The "core" is made with a lot of "eyes" taking care that not something "wrong" for the user enters the code base.
Then some marketing people both in and outside of Mozilla push something that is probably not passing the same strict reviews.
It points to the organizational problem in Mozilla.

Why would you assume that it does? Have you ever seen how big products like core Firefox binaries are written, reviewed and tested? I took part in that, and this doesn't look at all as part of that process. I see it's even not in the same repository where the "serious stuff" is. It's not the part of that process.
This looks like "let's give litte Perry and these marketing departments something to play, whatever, it's just an extension, who cares." So little Perry writes a description of the extension "MY REALITY IS JUST DIFFERENT FROM YOURS", the extension gets silently pushed to all the US users(!) (Firefox has support for that) who freak out, and the first response from somebody involved with that was "it was not supposed to be seen." You see, it was planned to keep the extension also "invisible" to the users -- Firefox has support that too! The extension was obviously not formally reviewed or formally tested, if the "invisibility" was the goal. Of course, it being "invisible" wouldn't be better. It's a misuse of the whole mechanism, compared to what Mozilla explained to the users. The mechanism was supposed to allow making "studies" from the behavior of the users who agree to take part in them. Instead, it was an attempt to a "viral ad" that was delivered to the whole Firefox using US population. There are multiple wrong decisions in this story.
Now I hope Mozilla does get the idea that the users do care.
It's not what you are but what your settings are, please go here and check what your browser reports under ACCEPT_LANGUAGE. If it is "en-US" you are considered a "US user" enough:
BTW: the extension we all talk about here has exactly this site that is used for checking the headers hardcoded inside, obviously in order for the developers to test their newly coded functionality with which they add an additional header entry in the request to some specific sites, specifically, the "main target" is a brand (I've given the link earlier on in this thread). It's obviously an advertisement for the US as that "main target" site is only meaningful to the US public. But it's obviously not the whole story.
If your language is not en-US it's worse than what I've understood.
