I have installed a new hard disk for my windows 7 computer. It is a new installation of windows 7. The existing disk is now disk F: on the computer. I made a new installation of thunderbird on the new disk. I followed your instructions and copied the profile onto the new disk. The local folders have been transferred but the address book and all the accounts have been lost. Is there any way to get the address book in particular back? If I run thunderbird from the old hard disk (by clicking on the name in the old program files folder) I get the same version up.
