Consequently, it will come as little surprise, that practically six weeks to the day since Firefox 8 made an appearance, Mozilla released Firefox 9 Final . Those looking for a slew of new features will be disappointed, but it does contain one major performance fillip that makes upgrading worthwhile
The most significant change over Firefox 8 is the addition of type inference to the JavaScript engine, which singlehandedly improves JS execution speed by 20 to 30%.
Other changes simply involve adding and improving support for web standards, including CSS3 and HTML5, building on previous releases. There are also a number of stability bug fixes.
