Required Thunderbird preferences

We provide a user.js configuration file in configuration/user.js that enable some preferences required by this theme to work.

You should already have this file installed if you followed one of the installation methods, but in any case be sure this preferences are enabled under Thunderbird's Config Editor:

• toolkit.legacyUserProfileCustomizations.stylesheets

  This preference is required to load the custom CSS in Thunderbird, otherwise the theme wouldn't work.

• svg.context-properties.content.enabled

  This preference is required to recolor the icons, otherwise you will get black icons everywhere.

For other non essential preferences checkout configuration/user.js.
