Well, you might be right that it is power users, but I know that extensions and greater extension freedom are one of the things that is the draw that keeps the remaining Mozilla Firefox users (like me) loyal. Basically I'm arguing power users are a disproportionate percentage of the remaining Mozilla Firefox user base, which is why things like supporting tracking protection and privacy measures also makes sense for them to focus on, even if the majority of people online might not care about this.

So, I'm glad they are expanding the extensions available. I just hope that this isn't tied to creating an account still. [EDIT] I was overjoyed to see that I was able to add an extension without creating an account. Yay!
