here are some suggestions from a user who tried to set up a new profile
and migrated his data into it.
I don't know whether Import/Export tools can handle address books.
Interesting reading is also
https://bugzilla.mozilla.org/show_bug.cgi?id=584014#c85 about a function
to "refresh" a profile in case it got somehow corrupted.
We might want to consider some of the items for future planning.

trying to reuse past address books mab files with the addressbooksynchronizer
extension is error prone. It gave me errors in importing one of the mab files.
I had to export it as CSV and re-import the addresses. In this way all the
mailing lists are lost, and I had to export them individually as CSV files,
which was a real pain. I really think that TB should learn to export/import
its address books in some JSON or YAML format preserving the mailing lists.
There is no easy way to export/import an email account configuration. TB
should learn to export/import account configuration in some structured text
format (JSON or YAML).
Creating new email accounts from scratch, they get set up with the "Keep
messages in all folders for this account on this computer" and "Syncronize all
messages locally regardless of age". IMHO this is looking for trouble.
Downloading many GBs of messages from each account quicly filled my disk
blocking my machine and risking data loss. I think that TB should default to
only sync locally /recent/ messages on IMAP accounts. The issue is made worse
by the fact that when you change the setup TB does not reclaim the space.
