Exactly this. Often with complaints about FF performance someone comes along and says something like the above, about JS or my laptop's hardware, or etc, but if Chrome, with all its shitty tracking, can make those same sites load just fine on nearly any machine, then FF should be able to do the same if it wants more users. I don't care about your browser's problems and exceptions to decent performance. I shouldn't be expected to filter the sorts of sites I visit for the sake of making sure they don't harm my delicate little FF instance. I just want the damn thing to work as other browsers apparently can.
