For what it's worth, I turned off tabs on top instantly, and do on any of the 5 or so computers I use. It just doesn't make any sense to me that the tab would contain the url input.
Meanwhile, I also install status4evah on all of them as well, because I actually USE that, and always did since Netscape 1.1 or whatever.
I also install the firefox 2.x theme.
I'm basically trying to keep the ui frozen in time as long as possible until they make it impossible for me to keep the UI moderately consistent withg the rest of my platform, at which time hopefully some less hateful browser will exist.
