-Bookmarks in weird position (right).
-Optional home button (why? doesnt everyone use home button always?)
-No fast scroll, press middle button down and scroll in any way (or maybe you have to enable it?)
-Too much information about browsing habbits, not easy to remove unwanted information on the startpage (or I did not look close enough).
-No new tab by double clicking on the top bar (you have to click on new tab area)
-Statusbar dissapears when not loading pages, dont know if that is good or bad, right now I prefer a static status bar.
-To surf anonymouse you have to run pron-mode. They should have developed a middle road instead of extreme and minimal privacy. You can only guess what Google is going to do with all this information that they are going to mine.
At least its fast. But I am going to stick with IE7 right now I dont like FF's interface and scrolling.
