Firefox 18 beta released with faster JavaScript engine, Retina support

Tools

Mozilla on Monday released the beta version of Firefox 18, which comes with a revamped "IonMonkey" JavaScript engine and support for Mac laptops that come with Apple's (NASDAQ: AAPL) high-resolution Retina displays.

IonMonkey offers significant performance improvements over the earlier version of its JIT compiler and is particularly suited for rendering complex JavaScript code, such as that found in online games. Aside from that, IonMonkey is expected to help in terms of code maintenance and future JavaScript compiler research, reports The Inquirer.

Other improvements in Firefox 18 include a browser-integrated PDF viewer, as well as the option to disable insecure content when visiting secure web sites. The latter was apparently just short of 12 years in the making, according to Johnathan Nightingale, Mozilla's vice president of engineering. The initial code for it was first added just four years before the appearance of Firefox 1.0.

For now, the final version of Firefox 18 is expected to ship on Jan 7, 2013 and the beta version can be downloaded here.
