The Golden Master build of OS X Lion has recently been released to Apple developers. New features include Mission Control, Launchpad, new Multi-Touch gestures, AirDrop, Versions, AutoSave, an all new version of Mail, and dozens of other new additions that make the software more user friendly, as well as more advanced in terms of functionality. It brings tons of enhancements, both aesthetically and under-the-hood, but most of them are about function. Scheduled to debut sometime this month, OS X Lion is the latest version of Apple’s desktop operating system.

Two workarounds have been included in a new version of Firefox, the popular open source web browser from Mozilla, following the discovery of one issue that caused the application to misbehave under OS X 10.7 Lion, and another that caused the Java plugin to fail to load.
