Yea, i agree. That Web Development toolbar always came in handy, along with other plugins and features that Mozilla was great for. Problem is that Speed definitely could have been better. Using Google Chrome for now to see how things go, haven't uninstalled Firefox just yet.
I also liked how Firefox rendered pages as oppose to IE. At a first glance, Chrome is similar to Firefox in terms of rendering. First thing i noticed was resized <img> tags display nicely on Chrome too and they definitely don't on IE

At least not all the time.
