Mozilla Firefox is a free and open source Web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. Firefox is also the second most widely used internet browser. Firefox uses the Gecko layout engine, which implements most current web standards in addition to several features that are intended to anticipate likely additions to the standards.
Firefox 9 is slated to implement a new technology called “type inference” which allows the browser’s JavaScript engine to process JavaScript code much faster than before, which ultimately leads to performance improvements when loading pages or JavaScript apps.
