thunderbird will not keep new contacts in address book
I have added new contacts to my address book. When I go back a day later to use them they are gone. I have to recreate them to send an e-mail. Also I create a group contact and the same thing. I can use it the day I create it but the next day it is gone, Thunderbird does not save it to my address book. What is wrong ???. This is very upsetting and time consuming.

The symptoms suggest your Address Book is corrupted.
It can be fixed by exporting the affected address book to an LDIF file and then re-importing it. If it's one of the two built-in address books, you will need to close Thunderbird, open its profile and delete the relevant *.mab address book file. For the Personal Address Book, this is abook.mab, and for Collected Addresses, it's history.mab.
Other user-defined address books will have names such as abook-1.mab; the challenge it to work out which is which. However, user-defined address books can be deleted within Thunderbird, simply by selecting them in the Address Book and using the delete key. So you don't need to fish about in the profile for these.

Oh, one more thing. You didn't say what OS you use. Thunderbird has for a long time had read-only access to the address book provided by OSX. So if you're using a Mac, it's possible that you simply aren't allowed to alter the OSX address book from within Thunderbird. (Though ISTR reading that this is being changed to permit the OSX address book to be edited via Thunderbird.)
