In Xulrunner applications, the defaults/pref/ directory under the application directory is not used for preferences, which means channel-prefs.js, being installed there unconditionally, is never going to be read.

FYI: The changes that caused this bug also landed on Aurora and are on beta as well now.

Comment on attachment 631062 [details] [diff] [review] Install channel-prefs.js in PREF_DIR when building Firefox as a XULRunner app [Approval Request Comment] Bug caused by bug 756325, which was a late landing on aurora (a few days before beta merge). User impact if declined: Only a problem for people building firefox as a xulrunner application. Risk to taking this patch (and alternatives if risky): The patch doesn't change anything for mozilla builds.
