Comment 153 for bug 10910

Just to add to this bug discussion my observation in bug #627648 that the about:support setting for user-modified parameters do not appear to change in any when you alter the global paper size, which may be related to why this is continually reset on version 'upgrades'. This trait makes the lack of correct system-based defaults even worse as every user's account has to be manually reset following any security fixes, etc, for Firefox and Thunderbird.
