I worked on Mozilla related tech for about eight years, mostly niche open source browsers. I couldn't even get patches that fixed known bugs that lost Firefox user data accepted. Important decisions seemed to take place in closed meetings, on closed wikis, on private IRC networks. Eventually I gave up. The Mozilla culture was insular rather than open. The further I've been from MoCo the happier I've been.

It's been a few years now, perhaps things are better? I'm not interested in returning to that world to find out.
