Customize Your ThunderBird

Use Mr tech or edit user.js from your profile:

// Download mail from all accounts on startup
user_pref(“mail.check_all_imap_folders_for_new”, true);

// Turn off extra sending window
user_pref(“mailnews.show_send_progress”, true);

// Click on throbber to go to Thunderbird Help:
user_pref(“messenger.throbber.url”, “http://evolua.ro”);

// Specify the time to display new mail alert (in milliseconds):
user_pref(“alerts.totalOpenTime”, 4000);

// Change the reply header
// 0 – No Reply-Text
// 1 – “[Author] wrote:”
// 2 – “On [date] [author] wrote:”
// 3 – User-defined reply header. Use the prefs below in conjunction with this:
user_pref(“mailnews.reply_header_type”, 3);

// If you set 3 for the pref above then you may set the following prefs.
user_pref(“mailnews.reply_header_authorwrote”, “%s said the following”);
user_pref(“mailnews.reply_header_ondate”, “on %s”);
user_pref(“mailnews.reply_header_separator”, ” “);
user_pref(“mailnews.reply_header_colon”, “:”);
// The end result will be [authorwrote][separator][ondate][colon]
