Documented Preferences
Last Updated: 2006-10-24

This page contains an extensive list of Mozilla preferences, and is a HTML conversion of the information contained in the Preferential extension. While it is not complete, it is one of the most comprehensive resources available on the Internet. Please e-mail GuruJ@mbox.com.au with any new preference descriptions or errata. This list applies to Mozilla Suite, Mozilla Firebird, Mozilla Thunderbird, other derivatives and all related extensions!

NB: All references to FOO or BAR are wildcards. Replace this with the number or text of your choice here (exactly which depends on the context) and Mozilla should pick up all preferences that match this pattern.
