More and more and more web sites that use JavaScript. Mozilla is well aware of this, and for that reason has decided to create a technology by which to improve future Firefox speed 18 in this kind of sites. Apparently the burden of websites that use JavaScript may be up to 26% faster.
Mozilla planning How to do this? IonMonkey Using a compildor just-in-time (JIT). Basically, what it will do is look IonMonkey general level code and perform optimizations, resulting in a charge of the site in less time for the new Firefox browser.
The first beta of Firefox 18 will be launched only in November, so until then we can not prove it.
