Now that FireFox has become such a bloated hog (currently running 201,000k for me right now), I’m more than willing to go to IE9 if they make it good.
Chrome is simple too sparse, but I use it as the default. Opera is too “busy”.
FireFox with NoScript and Adblock are the ideal browser. No blinking ads or popups, I love it.
Jesus! How many add-ons do you have? Ever think about turning some of them off? I use NoScript, AdBlockPlus, and Ghostery, and I’m running around 80 Mb (80,000 Kb). I agree that a browser should be agile, but lightweight has gone the way of the dodo!
With newer machines coming in with more than 4 GB RAM and hard drives reaching 3 TB, sure we want fast, but memory and hard disk footprints don’t much matter anymore.
