gecko/mobile/android/base/GeckoPreferences.java
Nathan Froyd dd857f3622 Bug 906088 - part 1b - add ArrayList getPrefs method to PrefsHelper; r=bnicholson
Related to the last patch, this is the lone place where we transfer an ArrayList.
Just move the code into PrefsHelper in case anybody ever wants to do something similar.
