Works perfectly. I love Thunderbird and all of the options available. Far better then that proprietary other mail app. This addressbook tab add-on solved my last customization. Simply installed, then right clicked on the tool bar, then dragged the AddressTab icon to the location I wanted. Really simple and works perfectly.
