Yes, this is exactly right, some things won't be for everyone. The best part of Firefox (for me, besides being able to have vertical tree-style tabs) is that more times than not, you can disable and/or hide the change you don't like, as demonstrated by the blog post.

Sure, I might not agree with every change they make to default choices but they at least let us power users configure the browser so it ends up just like how we want it to be, and for that I'm very grateful, as it tends to be uncommon in this day and age.
