Chameleon (formerly known as Theme Builder) is a graphical tool made to simplify the creation of themes for Mozilla. This tool gives users the ability to apply new graphic designs to the browser without changing its functionality. Individuals can use the tool to create their own personal themes while companies can "brand" the browser with their company colors and logo.
Total Recall is a crash recovery and session history feature for Mozilla. State information is regularly saved during a browsing session, so in the event of a browser or operating system crash Mozilla can be restarted and each previously opened window can be relaunched. This feature can also be used to track specific sessions that had been saved with this feature.
JSlib is intended to reduce the current amount of redundancy among Mozilla application developers who are trying to do similar things in different applications. By creating libraries of common useful routines, application developers can focus on creating original functionality for their own applications instead of dealing with messy XPConnect JS objects and worrying about which IDL methods do what and which are implemented on what platforms.
