My thunderbird crashed on me today and when I relaunched it it didn’t display any of my emails in it. I have tried restarting the macbook and relaunched thunderbird to no use. It starts as if starting for first time. Help!!!

Look here for help. If this answer is acceptable please remember to return and mark it.

I doubt that anything else might be helpful if rebuilding database was not able to bring your emails back. I looked online and found a utility by the name Mail Passport Pro. Check if it is able to get your emails from Thunderbird mbox files.
