Mozilla has released the latest version of its popular Firefox web browser, with improvements to the JavaScript rendering engine that could yield speed bumps of 30% over the previous release. According to Mozilla, the new Type Interface feature in the browser’s SpiderMoney JavaScript engine integrates with the existing compiler to deliver more efficient code in less time.

Other highlights of the release include Mac OS X Lion support, with Firefox for OS X now featuring a two-finger swipe gesture for navigating between websites. Also new for the Mac version is an enhanced Lion-friendly user interface, which also makes surfing the web with multiple monitors more straightforward.

Android users will also see an update to the browser’s mobile edition, with the latest release taking advantage of tablets and their increased screen size. The browser has now been optimized for tablet devices, with support for swiping, a tablet-friendly UI and new HTML5 form validation.

The desktop version has been given plenty of tweaks under the hood as well. Detecting a user’s Do Not Track preference using JavaScript is now possible and support for CSS, HTML5 and MathML has been improved. For the full list of changes, check out the Firefox 9 release notes.
