I'm puzzled. As a developer the sites I work on are (mostly) going to be hosted on my local machine. I usually don't bother with all the effort to set up SSL certificates for my development web server unless I've got an SSL-specific issue to investigate. Is this feature disabled for sites that are local? If not I'd expect I would just come to ignore it quite quickly. Then when I then look at the production version of a site I'm more likely to continue to ignore it as I've been conditioned into assuming it's a false indicator. At the same time, for normal web users I can see how such a warning could be helpful. But it seems normal editions of Firefox won't have this enabled by default. Or are my development practices unusual in some way?
