String: The unique (within this script) name for this value.
Should be restricted to valid Javascript identifier characters.

Any valid javascript value. Just note that it is not advisable to
store too much data in the Firefox preferences.

Parameters:

been set.
Returns:
When this name has been set...
The variable or function value as previously set.
When this name has not been set, and a default is provided...
The value passed in as a default
When this name has not been set, and default is not provided...
