The Contacts Sidebar extension for the email software Mozilla Thunderbird displays the address book - or books - in the sidebar of Thunderbird beneath the mail folders. The developer has added a helpful option to the extension: you can enable or disable its display in the sidebar with the F4 key on your keyboard. So, if you want access to it press F4 to display it, and F4 again once you are finished and no longer need access to it.
All the possibilities of the address book are available in the sidebar when you display it there: you can edit properties of your contacts or quickly choose a contact that you want to write a mail to. Here are some highlights taken from the description:
Search contacts quickly straight from your sidebar, and use advanced search parameters or combine saerch terms.Select recipients that you want to write to directly from the sidebar. Add them to all mail fields, To, CC, or BCC.Send contact information as vCard attachments to recipients.You can use drag and drop files or messages on contacts to quickly add file attachments to messages.LDAP address books can be populated automatically based on custom search queries.Use the hotkey F4 to display or hide the contacts list in Thunderbird's sidebar, or use View > Layout > Contacts Sidebar to toggle it.
Please Note: The Thunderbird extension on Mozilla's Add-ons repository for the Thunderbird email client has not been updated since 2007 so that it is no longer working in newer versions of the email program. While this is a sign usually that the developer has abandoned the project, it is not the case here.
The developer has not updated the extension on the Mozilla website, but updates have been posted on the author's own website which are still fully compatible with all recent versions of Thunderbird.
Just head over to this website and download the extension from here. To install it in Thunderbird do the following:
Note: The F4 shortcut does not seem to work anymore.
If you want fast access to the address books in Thunderbird without having to open a new window or menu for it, then you may find the Contacts Sidebar extension useful for that purpose.
