Mozilla on Tuesday shipped Firefox version 22 to address 17 vulnerabilities the browser.

Mozilla released four "critical" fixes for memory- and privilege-related bugs.

Firefox 22 also includes a new feature called “OdinMonkey," which is said to improve JavaScript performance for developers, and other new browser enhancements, such as Web Real-Time Communication (WebRTC) being enabled by default, allowing users to video chat, share files and carry out other real-time communications without the need for add-ons.

Most users will receive the new version automatically. For those who have disabled auto-updates, they can "Check for Updates" on the "Help" menu.
