People didn't like Australis UI for Firefox, but it wasn't a big change at all. It's not like GNome 2 -> Gnome 3 where most of the UI stuff was just thrown away (including the traditional and used by every OS, the window buttons).

#Mozilla mostly changed, it became maybe a little bit more corporate like, and less the rebel type which they were through the first 4 versions.

I want the freedom fighter Mozilla, not the "copy everything Chrome does wrong in a browser" Mozilla.
