Why is Firefox 4 trying to mimic Chromium?
 

Attachment 5303

Notice how LQ is pinned as an App Tab, just like the case with Chrome and Chromium? Notice also how the tabs are placed above the address bar, just like Chrome and Chromium?

Just why was this done and for what purpose? I'm posting this here because this screenshot was taken on Ubuntu and I'm using Ubuntu. I also tested Firefox 4 on Ubuntu before and didn't have this realignment of widgets.

Seems to me that the Ubuntu designers (in Fedora FF 4 Beta 7 has the "normal" look) don't want to mimic Chrome/Chromium, but how FF 4 looks in Windows 7, it has the same design there.
