Yep, you can count me in this group as well. The Firefox team goes out of it's way to make so many changes that just seem useless or annoying; it's baffling to me. It really feels like a team with too many devs and designers sitting around needing to create work. I very much doubt that's actually the case, but that just means it's a widespread management issue.
That said, it doesn't make me want to stop using Firefox because the only other option is Chrome which has bigger issues.
