Contacts Sidebar supports many locales: en-US, bg-BG, cs-CZ, de-DE, el-GR, es-ES, fr-FR, hu-HU, it-IT, ja-JP, pl-PL, pt-BR, pt-PT, ru-RU, zh-TW.
Many thanks to all. Contacts Sidebar displays all available address books in a sidebar in the 3-pane-window of Thunderbird. It makes all your contacts easy accessible from the main window to quickly write messages, or to edit the properties of a contact card.
As of version 0.6, the Contacts Sidebar also replaces the sidebar in the compose window. The sidebar in Thunderbirds main window and the sidebar in the compose window have the same context menu and share the same features.
