The update includes five (5) Critical and two (2) High security updates. Unfortunately, the issue introduced with version 29.1 that many users have experienced with slow shut downs resulting in the "Firefox is already running" warning remains unresolved. To get the update now, select "Help" from the Firefox menu at the upper left of the browser window, then pick "About Firefox." Additional information about the update is available in my blog post at Mozilla Firefox Version 30.0 Released.
