Firefox is terrible. It's embarrassing.
I do have Firefox occasionally choking, which annoys me as hell, but I'm on Firefox 8.I do get frustrated, but criticizing a software package that you get for freaking free, especially one that you ow so much to, with such a harsh tone really is unwarranted.
And it really is free in a not-for-profit way. The Awesome bar that the article mentions really saves you from making useless round-trips to Google / being exposed to Google Ads, even if this hurts Mozilla's revenues; on the other hand Chrome's primary reason for being is Google's control on the web, ensuring that Google's search remains the default, which is one reason the Awesome bar will never make it into Chrome.
Also, AdBlock Plus in Chrome has known bugs and limitations because of Chrome, because while Firefox is a platform, Chrome is a product that treats its users like idiots.
