I've been using Firefox 4 for a few weeks now. I don't care for the placement of the tabs. Using it on a netbook, I frequently close tabs in error because they are crammed at the very top of the screen and aren't very easily seen. I also don't the necessity of pressing the Alt key every time I want to use tools I have come to rely on. Couldn't they have stayed on the drop down options without being so hidden? Still, I prefer Firefox to Explorer and Chrome. I guess I'm stuck.
