I was originally going to merge this into user.js but decided against it since there's other content I might add here that would clutter up the user.js article -- e.g., prefs.js corruption, absolute paths in prefs.js, or deciphering the mail account entries in prefs.js. --wintogreen 16:26, 1 January 2006 (UTC)

For other possible article content

• Cases where you might want/need to manually edit prefs.js: Account order, Method 2 in Moving your profile folder
• Absolute paths in TB: bug 254668
• Corruption: last section in Disappearing mail (esp. about restoring from a backup)
