"Secondly, when it comes to performance, IE has been getting better with every version while Firefox has been getting worse."
Your point about the lack of out-of-process tabs is legitimate, but I'm unsure as to how Firefox is getting worse. Could you elaborate? As far as I can tell, Firefox 4 is better than 3.6 in terms of performance on virtually every measure.
I haven't used other browsers besides Firefox in years, so I'm not qualified to provide a comparison. What I can say is that on the "profanity uttered"/"hour of usage" metric, Firefox has been getting much worse. Hell, I used to praise it.
