Firefox 9 delivers "30% speed boost"
Mozilla released Firefox 9 today, with the browser update bringing stability and speed improvements.
“This type information is used during JIT [just in time] compilation to generate more efficient code; Firefox 9 includes modifications to the JaegerMonkey JIT compiler to use inferred type information," he said.
"This compilation mode, which is the default in Firefox 9, speeds up major benchmarks like Kraken and V8 by over 30%, and gives a large speed boost to many JS heavy websites.”
Alongside Type Interface, Firefox 9 also brings better theme integration and two-finger swipe navigation for Mac OS X Lion, enhanced standards support for HTML5, MathML, and CSS and several bug fixes.
The latest version is available from Mozilla's download centre.
