Firefox 18 Released With IonMonkey JavaScript Compiler


Mozilla has just released the latest version of Firefox browser for Windows, Mac, Linux and Android devices. As expected, it was released with the IonMonkey JavaScript complier which it says provides faster JavaScript performance for web games and other long lived web applications. IonMonkey replaces SpiderMonkey JavaScript engine which had been its JavaScript booster in previous versions. Mozilla says IonMonkey outperform SpiderMonkey by more than 25%.

To show off how IonMonkey performs, Mozilla is highlighting BananaBread, a 3D web game developed by its Developer Network in HTML5, WebGL and JavaScript.

To get Firefox 18 in Windows and Mac, go to the download page on Mozilla.org and download a copy. Or open your current version and go to Firefox –> Help –> About Firefox to get updated. Android devices can get it from Google Play Store.

  • Support for W3C touch events implemented, taking the place of MozTouch events
  • Improved responsiveness for user on proxies
