In my experience both on my home network and at work I find IE and Firefox are both slower, the former substantially slower in fact. At work I needed the HelpDesk to help out with some technical software I use in my work. The Tech Support guy started to use IE 9 because he needed to download a patch. He clicked IE 9 and while waiting for it to load he said it would have been better to have Chrome. I told him it was already there. He immediately shut IE 9 and started Chrome which loaded virtually immediately. I am not a big fan of Google for a few reasons but I have to call a spade a spade. Where Firefox is concerned I have in fact uninstalled it both at work and home because it was creating too many problems and I didn't have the patience to figure everything out. But when I was using it, while it was quicker than IE9 but certainly not faster than Chrome. Maybe browser speed depends on the ISP but even on my laptop it is exactly the same. So I am in complete agreement with the article.
