Is there a way to retrieve deleted email addesses?
I went to delete 1 contact from a group that had about 85 email addresses, and I must have failed to select a particular email address, so it deleted the whole group. Any way to get them back?

Lets start with your definition of a Group. Thunderbird does not have groups. It has Address Books and Mailing Lists. Was this an address book or a mailing list that you created in one of your address books?
If you deleted an address book I do not know of any way to recover it.
If you deleted a mailing list from your address book all you did is delete the list. All the contacts that were on that list will still be in the address book. Just recreate the mailing list.
