Servo Architecture: Safety and Performance

There seem to be a lot of people that are saying "oh, without XUL based extensions, Firefox is just a (worse) Chrome clone, so I might as well just use Chrome." I think what they might be missing is that Mozilla's conclusion is a lot like the people seem to be thinking here -- even though Chrome doesn't have the fancy extensions that are possible in Firefox, many many more people are using Chrome than Firefox, because they see it as a better Firefox. Clearly, that has something to do with either security or performance, where Firefox has a perceived lag. Mozilla is actively working to improve performance, and you may not want to switch to Chrome after all, because Chrome may instead be the poor man's Firefox (I personally think this is already the case, simply because with my 679 open tabs, Chrome would simply kill itself [44 loaded]).
