On the Mac, at least, it's painfully obvious that nothing matches. The look is a little off, but the behavior is way off. The scrolling doesn't work the same as native scrolling, nor do the context menus, the toolbars, the tabs, or the keyboard shortcuts. You can't do anything in Firefox without being reminded that you're using an app which is not like any other app on your Mac.
It seems they've been struggling to get more Mac developers for a long time. Unfortunately, their toolchain is so foreign to Mac developers, too, that people don't want to learn it. It's a chicken-and-egg problem.
This problem is easily solved on Windows by having no two programs looking the same :D (even those made by Microsoft and even those actually part of Windows)
