Tech Update: Firefox 9 with faster Javascript released

Firefox 9, the newest iteration of Mozilla's popular browser, has been released. 

Along with the usual bug fixes, the biggest new feature this cycle is the inclusion of something called Type Inference, which Mozilla says improves benchmark performances in Javascript by 30 percent and can give "a large speed boost to many JS heavy websites."

The other big features include better integration into Mac OS X Lion and a Do Not Track status via Javascript. Click here for the full release notes, or head to the download page for the newest version of Firefox.
