It now asks for a Master Software Security Password. I didn't have one in version 2. Now it won't let me access my inbox because I don't know the new password I didn't have. As a result, I have effectively lost my entire inbox. Reproducible: Always Steps to Reproduce: 1. reboot 2. launch thunderbird 3. still asks for password I never had. I eventually have to "cancel" to proceed Actual Results: can't access inbox I only hope that it hasn't encrypted my inbox preventing me from rolling back to Thunderbird 2 so I can get my email back.
The inbox isn't protected, only the passwords are encrypted with a masterpasswords. Please follow http://kb.mozillazine.org/Master_password#Resetting_the_master_password
FOLLOWUP: Investigation showed that it DELETED my inbox. this was coincidental with the prompt for a non-existent master password that I assumed that it was just blocking access to the inbox. An examination of the file structure showed that the file size of "inbox" and "inbox.msf" is 0. (the inbox was 1.2 GB immediately before the upgrade)
